Based on "Getting Your Club to Write," by Dennis Westman, Minnesota Mineral Club, in S.C.R.I.B.E. Newsletter, Oct-Dec 2004 and On Writing, by Stephen King, Simon & Schuster, 2000.
Step 1: Pick a subject that interests you. It could be a story about something you've done (collecting agates, panning for gold), or it could be research about something you've never done (digging up dinosaur fossils in Antarctica).
Step 2: Map it out. Planning is everything. You have to figure out how to get from A to Z in your story. Outline with pencil & paper the bare bones of your story. Jot down important things you "must have" in the article (where the collecting took place, how many gold nuggets you found). Keep in mind the five W's of journalism: Who, What, Where, When, Why. Your outline should include all of them.
Step 3: Start writing. Don't worry about spelling, grammar, or punctuation. That's what editors are for. Refer back to your outline, use your own voice, and let the story flow naturally, as you would tell it to a friend. With your outline, you won't forget all those exciting tidbits you might have left out if you were just spouting off to your friends.
Step 4: Plot, characters, scenery, and dialogue. If you were submitting a movie script, you'd be kicked out of the producer's office for leaving any of these items out. A story can't be a story without them; it won't "sell" to the audience. Let's cover those four items in the next few steps.
Step 5: Plot. Writing is not rambling. The ideas of Beginning, Middle and End are universal to all stories. Usually a normal timeline is followed, where "what happened next" is the rule. The most common exception to this rule is a flashback ("The saber-toothed cat plunged into the sticky tar pit, unaware that his fossilized bones would be left for us to find 20,000 years later.").
Step 6: Characters. The people who are in the story: it's your job to describe them, from height, age, hair color and clothing, to habits and attitude. Simply writing that "Jake drove us as far as Mesquite," is not the same as writing, "With Jake's spiky green hair and his crazy attitude towards other drivers on the road, we feared we'd never make it to Mesquite." Strictly, only people can be characters, but no one will complain if animals, plants and rocks have personalities in your story as well.
Step 7: Scenery. The setting of the story includes the natural landscape and the man-made objects in it (roads, tools, vehicles, buildings, etc.). This is where you can really get imaginative with descriptions, since no two people see the same object in the same way. If you want to describe a yellow crystal as "lemony" or an empty desert as "filled with the promise of geological secrets," it's up to you.
Step 8: Dialogue. What do the characters say in the story? Though many stories are written without dialogue, it's usually more interesting if you include some. Writing that "Julie was excited about her fossil find," is less interesting than writing, "We all heard Julie yell, 'I think I found a complete tooth!'" Internal dialogue - describing your thoughts and emotions - also adds to a story, making it more compelling than a "just the facts, ma'am" report.
Step 9: Go back and revise. You've written your story by now, following Steps 1 through 8. But it's pretty rough; it could be better. Go back over it, maybe read it out loud to a friend, add a few things you forgot, or cut out some unnecessary sentences. Substitute a better word or phrase for the ones you wrote originally. Polish it. Rockhounds all know that most everything looks better with a good polish on it.
Step 10: Give your story a title. A catchy title is always a plus, and will draw readers to your story. "Titanic" is a better title than "An Interrupted Ocean Voyage." But don't go overboard! A simple, appropriate title is still better than a contrived, overly cute one.
Step 11: Space is a consideration. Everyone who writes for publication in print (bulletins, newspapers, magazines) must deal with space limitations. Cutting your work is often necessary. Writer Stephen King says that you should always cut out or condense at least one-third of everything you've written. It's like over packing for a trip: when you return home, you realize that you didn't need to cart around all that extra baggage. In the real world, an editor will have to cut your story if you don't do it yourself.
Step 12: Prepare for next time. If you weren't entirely happy with your first story, think about future possibilities. Carry a small notebook with you and jot down observations about people, scenery, conversations, etc. You'll be surprised how easily this will guide you in completing Steps 1 through 8.

It's common knowledge that we live in an ever-more-litigious society. People are now suing (and winning!) because they spilled coffee in their own lap! For those of us who volunteer to serve as officers or directors of our societies, we can be held personally liable as the result of a lawsuit brought by other members of our club or the general public for various claims, which would not be covered, under the Federation's general liability insurance policy (provided by Chubb insurance). Such claims could include: denied opportunities, denied non-monetary compensation, hostile work environment, discrimination, harassment, displeasure with a policy decision, disagreement with a decision regarding an expenditure of club funds or an individual or organization that feels has been harmed financially because of a decision of the board, just to name a few. Without the proper insurance protection, you would have to spend your own money just to defend yourself. So, even if you "win" the lawsuit, you "lose" all of the money you spent defending yourself.
The insurance policy designed to protect directors and officers of non-profit organizations is called Directors and Officers Liability Insurance (or, "D&O" insurance for short). The Federation has been working diligently to obtain such coverage for quite some time and was recently offered a policy, which the directors of each society who were in attendance at the recent CFMS Directors' meeting in Roseville voted to pursue. This new program would have allowed individual clubs within the Federation to purchase coverage for their own directors and officers at a cost of $250.00 per year - a VERY good insurance value. However, complications arose following the Directors' meeting which now forces the Federation to pursue coverage through another insurance carrier.
As soon as an alternate program becomes available, I'll provide a preview in the CFMS newsletter.

Plants have been used by prospectors searching for minerals since the Middle Ages. Some plants favor soils that contain or have an abundance of a particular element. Many prospectors use the desert trumpet as a gold indicator, even though it has not proven to be a true gold indicator. Plants of the mustard family excel in absolving uranium and may be of use to the geobotanical prospector who is searching for uranium minerals.
The California poppy is a known indicator of copper as it requires copper to exist.
Some copper compounds are soluble in water, so the presence of poppies does not necessarily indicate that there are copper minerals in the immediate area. Roadside occurrences of poppies should be ignored because of the presence of various contaminants from the passing cars and trucks.
The presence of poppies in the open desert is much more meaningful. Near San Manuel Mine, north of Tucson, poppies grow in profusion on the ground known to be mineralized ground. Against non-mineralized ground, the poppies terminate abruptly, and the fault line can be traced by the poppies. Often, dumps at copper mines are completely covered by poppies.
Since gold, silver and other metals are frequently associated with copper, the presence of the California poppy can be a clue to the possible presence of valuable metal deposits. For the rockhound, many of the primary and secondary copper minerals are of interest. They include chalcopyrite, turquoise, malachite and many more.

The September birthstone is the Sapphire and the flower is the Aster.
SAPPHIRE, the non-red variety of corundum.
VARIETY INFORMATION:
Variety of: Corundum Al2O3;
Uses: Gemstone;
Birthstone for: September;
Color: Various colors, except for red;
Index or refraction: 1.76 - 1.78;
Birefringence: 0.009;
Hardness: 9;
Cleavage: None, although there is a rhombic parting;
Crystal system: Trigonal;
Pleochroic: Strongly.
Sapphire is the non-red variety of corundum, the second hardest natural mineral known to mankind. The red variety of corundum is Ruby. Sapphires are well known among the general public as being blue, but it can be nearly any color. The blue color is by far the most popular color for sapphire but orange-pink, golden, white, and even black have generated much interest in the gem trade. Oriented rutile crystal inclusions cause a six-pointed-star light effect (called asterism) to form the popular Star Sapphire.

GEMS OF SEPTEMBER.
These were traditionally sapphire or chrysolite (olivine/peridot). The modern assignation is still sapphire, although mystical assignments have been made to agate and aventurine. If you check the astrological stones, Virgo (August 23-September 22) has jasper, carnelian, jade and sapphire for birthstones and citrine as a planetary stone. Libra (September 23-October 22) has opal and lapis lazuli for birthstones and sapphire as a planetary stone.
Sapphire has more mystery and legend surrounding it than most stones. The ancient Persians believed that the earth rested on a giant sapphire whose reflection gave the sky its color. You needed a sapphire to consult oracles or spiritual guides. It is supposed to provide calm, strengthen positive beliefs and bring good luck. Sapphires were worn by kings as a powerful defense against harm.
The six-sided crystals of corundum form in pegmatitic and metamorphic rocks and can be any color as well as the cornflower blue we love, all vivid or gentle shades of pink, gold, violet, orange, dark green, lemon yellow, and the brilliant pink-orange called Padparadshah.
A maiden born when autumn leaves
Are rustling in September's breeze,
A sapphire on her brow should bind,
'Twill cure diseases of the mind.
Lapis Lazuli/Lazurite, the only gem rock, is considered by some to be formed of at least a half a dozen feldspathoids that form in alkaline rocks with low silica instead of feldspars. This deep blue variety of lazurite (which is translucent with dull luster) has a hardness of 5-5 1/2, is a sodium aluminum silicate with chlorine and some sulphur (Na,Ca)8[(S04,S,Cl)2(AlSi04)6]. It is similar to Sodalite, another sodium aluminum silicate with chlorine, no sulphur, Na8Al6Si6O24Cl2. They are distinguished by the presence of pyrite inclusions in lapis lazuli. Lapis may be any shade of blue from sky-blue, greenish blue, to even royal or dark blue. It has a blue streak. Sodalite may have yellow, green and red veins and has a colorless streak.
Lapis was found in the crystallized limestones of Afghanistan, according to legend, 5,000 years ago. The earliest material was not uniformly gem quality, but it has always been considered an excellent ornamental jewel. It was the official stone of the dynasties of the Nile 2,000 years ago, highly valued by the ancient Pharaohs and used for royal seals, rings, and jewelry. It was also powdered for medicines, makeup and paint. The older traditions attributed good luck, love, power and wealth to those who wore it next to their skin. It is the face mask of the young King Tut. Lapis is found on Greek figures dating to 1,200 BC on Chilean ornaments of 2,000 years ago.

On July 14, Jim Brace-Thompson gave an invited presentation to the Conejo Gem & Mineral Club. The talk was entitled "The Monterey Formation of Carmel Valley: A Tour of a Miocene Seashore". It was built upon a talk he gave three years ago to the Ventura club. He illustrated the talk with slides showing the geologic history and economic importance of the Monterey Formation, fossils that can be found in a half dozen localities between Carmel and Greenfield, and scenic views of a California valley that remains largely undeveloped, with fields of wildflowers, open ranchland, and live oak savanna. To conclude the talk, the audience was invited to see representative samples from Jim's fossil crabs, clams, scallops, leaves, fish remains and other 10- to 12-million-year-old creatures collected over the course of a decade living in the Monterey area.
Jim Brace-Thompson.
On August 6, Steve and Susan Mulqueen prepared a new exhibit at the California Oil Museum titled "Trace Fossils". Specimens in the display include animal footprints, crab claw marks, insect burrows, tail drag marks all in sedimentary rocks and a woodpecker hole in a sample of petrified wood. The exhibit will be at the museum for 3 months.
Steve Mulqueen.
Editor's Note: The California Oil Museum is a great place to visit. Stop by and see Steve and Susan's new exhibit. Many thanks to the two of you for doing this one and all the ones in the past. They are great publicity for the Club.

Tri Club Fieldtrip:
Trona, CA, October 7-9, 2005.
On Saturday and Sunday we will take advantage of the activities offered at the Searles Lake Gem and Mineral Society's annual Gem-O-Rama. In addition to the usual exhibits and dealers, there are three unique and spectacular field trips offered; and the Trona Community has a great pancake breakfast. In addition we will head North of Trona on our own on Friday. (Note: There is a $8.00 to $10.00 fee for each trip.) Before you go check out their web site: http://www1.iwvisp.com/tronagemclub/.
Directions: From Mojave follow Hwy 14 North. Just before Red Rock State Park turn right on Redrock-Randsburg Road. Take the Garlock Turnoff (after about 12.1 mi.). When you reach Hwy 395 (about 8.2 miles), turn left (north). Follow Hwy 395 about 3.1 miles, then turn right on Searles Station Cut-off Road. Continue for 6.4 miles to Trona Road. Turn left (North) on Trona Road. Continue 8.5 miles, then turn right on SR 178. Follow this road into Trona. The show site (Gem and Mineral Building) will be on your left. To find the campground proceed north for 5.3 miles. It is on the right side of the road.
Camping: We will camp at the Valley Wells Recreation Area, located 5.3 miles north of the show. There are toilets and water available, but no hook-ups for RV's. There is a $5.00 fee per vehicle. Hotels are available in Ridgecrest, about 20 miles from Trona. We will arrive at the Valley Wells Campsite by 10:00 a.m. on Friday morning.
Fieldtrips:
Friday. We will meet for our Friday fieldtrip at the Valley Wells campsite (mentioned above). Departure is scheduled for 11:00 a.m. We plan to visit the Queen Lace Travertine site. I hope to have a local resident guide us to some other sites as well. If you plan to attend on Friday PLEASE LET ME KNOW (phone: 805-647-4393 or e-mail: clintwise@hotmail.com).

Never underestimate the power of stupid people in large groups. - Gringo Gazette May 2001.
Table of Contents.
At home or on the road, you should be aware of carbon monoxide. If you are driving your RV or an auto and you begin to feel sleepy, think - "carbon monoxide." It can kill you and those you love quickly. The same thing applies at home or in a motel. First, get some fresh air, and then investigate to see if you have an exhaust leak from your engine or some appliance. If you are driving, you can safely continue if you have PLENTY of FRESH AIR until you can get somewhere to have it repaired. At home, or in a motel, open all the windows, and turn on any available fan. But, whatever you do, don't drive while you are not fully awake. And now a word from the City of Phoenix Safety bulletin, 6/20/00.
CARBON MONOXIDE.
Carbon monoxide (CO) is an odorless, colorless, deadly gas. It can kill you before you know it because you can't see it, taste it or smell it. At lower levels of exposure, it can cause health problems. Some people may be more vulnerable to CO poisoning such as fetuses, infants, children, senior citizens and those with heart or lung problems. When an individual breathes in CO, it accumulates in the blood and forms a toxic compound known as carboxyhemoglobin (COHb). Hemoglobin carries oxygen in the bloodstream to cells and tissues. Carbon monoxide attaches itself to hemoglobin and displaces the oxygen that the body organs need.
Carboxyhemoglobin can cause headaches, fatigue, nausea, dizzy spells, confusion and irritability. Later stages of CO poisoning can cause vomiting, loss of consciousness and eventually brain damage or death.
Carbon monoxide is a by-product of combustion of fossil fuels. Fumes from automobiles contain high levels of CO. Appliances such as furnaces, space heaters, clothes dryers, ranges, ovens, water heaters, charcoal grills, fireplaces and wood burning stoves produce CO. Carbon monoxide usually is vented to the outside if appliances function correctly and the home is vented properly. Problems occur when furnace heat exchanger cracks or vents and chimneys become blocked. Insulation sometimes can trap CO in the home.
The Consumer Product Safety Commission recommends installing at least one carbon monoxide detector with an audible alarm near the bedrooms. If a home has more than one story, a detector should be placed on each story. Be sure the detector has a testing laboratory label.
The following is a checklist for where to look for problem sources of CO in the home:
A forced air furnace is frequently the source of leaks and should be carefully inspected.
Measure the concentration of carbon monoxide in the flue gases.
Check furnace connections to flue pipes and venting systems to the outside of the home for signs of corrosion, rust gaps, holes.
Check furnace filters and filtering systems for dirt and blockage.
Check forced air fans for proper installation and to assure correct air flow of flue gases. Improper furnace blower installation can result in carbon monoxide build-up because toxic gas is blown into rather than out of the house.
Check the combustion chamber and internal heat exchanger for cracks, holes, metal fatigue or corrosion. Be sure they are clean and free of debris.
Check burners and ignition system. A flame that is mostly yellow in color in natural gas fired furnaces is often a sign that the fuel is not burning completely and higher levels of carbon monoxide are being released. Oil furnaces with similar problems can give off an oily odor. Remember you can't smell carbon monoxide.
Check all venting systems to the outside including flues and chimneys for cracks, corrosion, holes, debris, blockages. Animals and birds can build nests in chimneys preventing gases from escaping.
Check all other appliances in the home that use flammable fuels such as natural gas, oil, propane, wood or kerosene. Appliances include water heaters, clothes dryers, kitchen ranges, ovens or cook tops, wood burning stoves, gas refrigerators.
Pilot lights can be a source of carbon monoxide because the by-products of combustion are released inside the home rather than vented outside.
Be sure space heaters are vented properly. Unvented space heaters that use a flammable fuel such as kerosene can release carbon monoxide into the home.
Barbecue grills should never be operated indoors under any circumstances nor should stove tops or ovens that operate on flammable fuels be used to heat a residence.
Check fireplaces for closed, blocked or bent flues, soot and debris.
Check the clothes dryer vent opening outside the house for lint.
The above applies equally to our motor homes also.

Most of us are sight oriented when we study rocks and minerals. Once, though, I was asked to give a program on minerals for the Minnesota Society for the Blind. As I was preparing this, I was impressed by the number of properties minerals have that can be sensed with the hands. It's worthwhile reviewing some of these as they are good identification tools for any one.
Density.
Density (or specific gravity) is one of the more familiar ones. This is the mass per unit volume. As an example, think of suitcases. They have a certain volume. When they are empty, they have little mass, thus a low density. Put clothes in them and they get heavier for their volume. If you're a typical rock collector, you have probably put rocks in your suitcases and increased their density immensely, much to the annoyance of airport luggage handlers.
Mineral densities can be evaluated the same way - by "hefting" them. If they have a medium density, they will feel about normal in mass for their size. If they are low density, like pumice or muscovite, they will feel light. If they are higher density, like garnet, galena, copper, barite or magnetite, they will feel heavy for their size. There are, of course, many ways to measure this density precisely, but "the heft test" still is a useful field test requiring no expensive instruments. You can fine-tune your approach by practicing hefting known minerals.
Tenacity.
Another property that can be appreciated with the hand is tenacity - the resistance of a mineral to mechanical crushing or bending. Brittle materials will break when stressed. Most minerals are brittle.
Malleable minerals, such as copper or gold can be flattened into sheets. Those who collect on the old copper mines in Michigan's Keweenaw Peninsula are aware of the resistance of copper-bearing rocks, and the spiny feel of the broken copper edges.
These minerals are also ductile meaning that they can be drawn out in the form of a wire.
Some minerals like chalcocite or gypsum are sectile, meaning they can be cut with a knife. Gypsum is soft enough to be cut by a fingernail. Some minerals, like the micas, are elastic and can return to their original shape after being bent. Some minerals like talc are flexible. Once bent, these minerals stay bent after the pressure is released.
Smoothness.
The smoothness or slipperiness of a mineral's surface can also be used as a tool. Talc feels slippery. Serpentine feels greasy. The fibrous character of splintery or asbestiform minerals can also be sensed.
Wettability.
Other minerals have distinct surface properties related to their wettability. This has to do with the way particular atoms on the surface of a mineral interact with water or other materials. Chrysocolla becomes sticky when moist, as do many clay minerals. Some clay minerals, such as those in the smectite group, actually swell when they absorb water and lose their strength. This is one reason why so many Western roads (where smectites are common in the soil) are good when dry, but become slippery mud holes after a rain.
Diamonds do not wet with water. If a pile of crushed minerals is saturated with water to become a slurry, then run over a grease (such as Vaseline) the uncoated diamonds will stick to the grease while the well-wetted minerals will slide right by. Beryl, corundum, rutile, spinel, topaz and zircon are other minerals gangue* that wet with difficulty.
The capacity of dirt to slide off of mineral surfaces also affects their cleaning. People who remark to me that datolites can be recognized on the mine dumps of the Keweenaw by the way the dirt seems to slide off of them are observing this property.
Minerals are great to look at, but the enjoyment of their properties spans all the senses.

Azurite is a prized and beautiful mineral which has always been a favorite of both dealers and collectors. Its brilliant azure blue color accounts for its name.
Azurite is always azure blue and, being a carbonate, will react readily with dilute hydrochloric acid making it a very easy mineral to identify. Its variable crystal forms, in combination with green malachite, create some of the world's most attractive mineral specimens. Azurite is less common than malachite but has the same origin and associations.
Numerous worldwide locations have produced prime specimens and include Lyons, France; Tsumeb, Nambia; Touissit, Morocco; and Broken Hill, New South Wales, Australia. The best known localities in the United States are the Bisbee and Morenci Areas of Southern Arizona.
Azurite is found widely distributed with numerous copper deposits in a number of other states. In Pennsylvania, azurite occurs sporadically in the copper deposits of Rossville and in the Columbia and Sullivan counties copper and uranium deposits. At Easton, PA, it has been found on rare occasions associated with malachite.
Azurite is most valuable for quality mineral specimens but is also a minor ore of copper.

A process which took nature hundreds, thousands, or perhaps millions of years to complete cannot be covered in a few words, but let's take a simplified look at their creation.
First came the raw materials - silica (silicon dioxide (Si02). This compound is a combination of silicon and oxygen and is a major rock builder in the earth's crust, being second only to the compound water in abundance. With silica so common, gems should be everywhere, but their formation depended upon conditions and this is where our story begins.
About 400 million years ago the Pacific Northwest began to rise from the sea. In a succession of volcanic upheavals a landmass rich in silica was created. Occasionally these lavas cooled so rapidly they formed a volcanic glass - obsidian. Generally, however, volcanic masses cooled slowly, tended to crystallize and were porous, eventually breaking down to release minute particles of silica. This free silica, in turn, was dissolved by acids in percolating ground water, then transported and finally deposited as concentrated liquids in subsurface cavities. Experts differ on how the liquids eventually became solids, however, the following basic silica forms were the result.
Crystalline - Silica deposited in obvious crystal forms and known as quartz or rock crystal.
Opaline - Silica form similar to chalcedony, but totally non-crystalline, more porous and containing small added amounts of free water (3 to 14 percent) held within its structure rather than its chemistry. Gem opals are of this form.
Cryptocrystalline - Silica deposits of microscopically fine-grained, almost non-crystalline masses known as chalcedony. Chalcedony characterizes agate and jasper.
Each of the silica forms occurred within cavities of previously formed rock and are termed secondary deposits. How each formed, however, depended largely on where it formed.
Individual gemstones, when found in gravel bars or loose soil, are usually a long way from their birthplace, having rolled and tumbled with the eroding forces. Generally the surface landmass of their origin has long since crumbled and vanished. Some gems, however, are still embedded where they developed and show that each basic type resulted from its own characteristic surroundings.
Agate: The result of chalcedony which filled empty gas pockets or cracks in otherwise solid rock, forming as nodules or seams. Since only limited amounts of foreign materials were included, the stone is fairly pure and ranges from clear to translucent when held to the light. Not all agates formed this way, with the two exceptions being thunder eggs and fossils.
Recognizing and Testing Agate: The mineral world has many look-alikes, but not all have gemstone quality. To avoid filling your pockets with excess rock, three simple tests can be made.
Luster: Look for even textured, non-granular material ranging from clear (glasslike) through translucent (semi-clear) to opaque (blocking out light). Rough specimens may have a glassy, waxy, pearly, or even dull appearance and can be better judged when wet. Agate: Waxy, clear to near opaque. Jasper: Waxy to dull and opaque. Opal: Pear-like, clear to opaque.
Fracture: Broken edges are usually conchoidal (cupped, shell-like fractures as on a chunk of glass). Water-worn pebbles often show curved crescent-like surface markings. An exception to this is opal, which tends to be brittle and more angular in fracture.
Hardness: Part of the reason these are termed gemstones is in their ability to polish well and withstand abrasion. They rank between 7 to 7.5 on the Mohs hardness scale.
Probably no gemstone is known in a greater variety of colors and patterns than agates. And, like fingerprints, no two of these are ever exactly the same. Recurring agate characteristics, however, have been given appropriate names such as: White or Milk, Turtle-back, Coated, Snakeskin, Blue, Amethystine, Carnelian, Sard, Polka Dot, Sunset, Enhydro or Water Agate, Fortifaction, Iris or Rainbow Agate, Banded, Sardonyx, Grape, Eye or Orbicular Agate, Tube or Pipe, Angel Wing, Dendritic, Moss, Plume, Flower, Sagenite, and Ellensberg Blue.

Polishing Oregon Picture Rock - After cutting, sand on the 22-grit sander, then move to the 6-grit sander. Polish with cerium oxide. Use no water to wet the sheet at first polish. Spray the wheel with a diluted solution of cerium oxide, and polish lightly without pressure until you have worked it dry. Then wet the wheel again and work until the stone becomes dry again. Final polish is brought out by spraying the wheel with cerium oxide and working, keeping wet about two minutes. Wash and dry off your cab or picture. This will produce a beautiful finish. - By Greg McGill, The Glacier Drifter 03/00 via Breccia 8/05.
Double the life of your diamond blade by keeping the oil clear and the feed low. Adding 1/4 to 1/2 cup liquid detergent to the oil acts as a coagulant and holds the grit to the bottom of the reservoir. - From Breccia 11-99 via MOROKS Monrovia Rockhounds Newsletter 6/05.
Drilling Plexi-Glass - A regular drill bit can be used to drill plexi-glass, by grinding the shoulder on the tip of the bit to remove the sharp angle. This prevents the chipping that would normally occur from a regular drill bit. - Strata Gem, Tooele G&M Society, June 2005 via Quarry Quips, Wichita G&M Society, June 2005.

Although silver was discovered later than gold and copper, it has been known and used by humankind since prehistoric times. Heredotus, the Greek historian, knew of silver used to make coins and beads, exploited from the river sands of the Pactolus in Lydia. The Chinese wrote of silver metals in 2500 B.C. In the earliest prehistoric strata at the site of Troy, considerable deposits of silver and gold treasure have been excavated. Among the artifacts, silver bracelets and gold earrings, ornaments placed in a silver cup and more than 8000 beads were buried in the ancient city 2000 years before Christ.
The most ancient silver mines of importance were in Asia Minor and on islands in the Aegean Sea. The Romans obtained most of their silver from Spain until supplies became scarce during the Middle Ages. After the discovery of the Americas in 1492, Mexico became the largest silver producing country in the world. Canada and the United States also produce significant amounts of silver.
Silver is a lustrous white metal widely distributed in nature. In ores, it is commonly associated with gold, lead, and copper. Much of the world's silver is obtained as a by-product of smelting these other metals. Horn-silver (AgCl) is found in the oxidized portions of ore-bearing material near the surface. Small amounts of silver in the oxidation zone form as the more complex compounds erode and weather. At deeper levels silver occurs as sulfides, arsenides andrnonides (compounds of silver with sulfur, arsenic and antimony). In these deposits, formation is the result of deposition from primary hydrothermal solutions. Argentite occurs in low temperature hydrothermal veins in association with other silver minerals or sometimes in the cementation of lead and zinc deposits.
When found in a metallic state, it is called "native silver". Native silver usually occurs in dentritic and wire-like forms which are aggregates of minute crystals. Silver may also occur in thin sheets or in large masses. In Kongsberg, Norway, magnificent crystalline wire specimens occur in association with sulfides, calcite, barite, fluorite and quartz.
The world's largest specimen of massive silver was mined in Aspen, Colorado, and weighs in at 844 pounds. On the Keweenaw Peninsula of Michigan, small amounts of primary native silver can be found in association with native copper. In Mexico, the Guanajuato Mine has been in operation since the year 1500 A.D. During that time, more than 500 billion kilos of silver have been mined.
About 3/4 of the world's silver production is used for monetary purposes, either as coins or as bullion that governments hold to redeem paper currency. The leading industrial use of silver is for the manufacture of tableware and jewelry. The second largest consumer is the photographic industry. Compounded with bromine or chlorine, silver forms salts which register light and shade on photographs. Mm silver had the highest thermal and electrical conductivity of any substance, making it ideal for use in electronic equipment. Silver is second only to gold in malleability. One ounce of silver can be drawn into wire 30 miles long. A silver leaf can be beaten to a thickness of 1/100,000 of an inch.

Wire wrap jewelry has recently gained popularity among all groups of peoples. For a small investment, any person can have a unique piece of wearable artwork. Bold, angular designs or smooth flowing curves can change a common gemstone into an heirloom. Ancient Phoenicians are credited with the creation of wire wrap jewelry, but the art goes back nearly 1,000 years earlier.
In the Biblical record, detailed instructions are given to Moses to construct the tabernacle and the priestly garments and attire, including Aaron's breastplate. In Exodus gems are listed; sardius (ruby), topaz, carbuncle, emerald, sapphire, diamond, jacinth, agate, amethyst, beryl, onyx and jasper. All were to be set in gold filigree.
Filigree was gold or silver hammered into thin sheets, then cut into thin strips and the edges filed smooth, thus making wire. The wire was woven into a basket or filigree and set into the breastplate. Later in Exodus, more detailed instructions were given about setting other gemstones into the rest of the priestly garments. Biblical scholars have placed this event near 1446 BC, nearly 1,000 years ahead of the Phoenicians.
There was a change in the Egyptian sarcophagus around 1900 BC, about the time that Joseph traveled to Egypt and brought his family there to avoid the famine in Israel. A sarcophagus was layered with fine sheets of gold prior to that time, but about 1900 to 1800 BC the sarcophagus changed to include woven strands of gold and silver, suggesting that the Hebrew artists brought this art form to their new homeland.
Wire was produced this way through the rise of the Phoenician empire. Phoenician culture thrived on arts and performance. As a semi-nomadic group of people, they took their art forms across the known world.
At the height of the Phoenician Empire, from 1250-500 BC, their jewelry was prized throughout the world. When the Greek navy came to power, the Phoenician trade started to dwindle and finally was engulfed totally by the rise of the Roman Empire. Although Roman culture was to absorb other art and cultural ideas into their own, the wire wrap art was abandoned for more traditional silversmith techniques. The earliest reference to drawn wire was in the 8th century in France. During the Medieval period, knights brought wire back to England to make chains and mail for their armor. Gold and silver wire were drawn in France and transported back to England. The earliest mention of wire production in England was 1465. Wire wrapping was limited to fastening crucifixes and other religious symbols to lanyards and chains.
During the late 1800's the Bohemian culture used wire to string chips of polished glass and stone beads to make necklaces and bracelets. This was popular among the European aristocracy for nearly 50 years. These hand-forged chains were so popular that if you were found not to have an authentic Bohemian piece of jewelry, you were shunned and scorned.
From 1837 to 1901 in the Victorian Age, the most popular pieces of jewelry were the cameo. Wire art combined the two most popular forms of jewelry of the time: sculpture and cameo. The truest form of wire art sculpture has only recently been seen as artists introduce this art form into almost every culture of America. Hundreds of artists now create rings, pendants, pins, hair barrettes, brooches, bracelets and stick pins. Modern wire artists combine gemstones, beads, antiques and even mineral specimens with gold, silver and gold-filled wire. Some artists even combine different types of metal for even more unique work.

Definition of the Month.
Trace Fossils.
Trace Fossils are features found in sedimentary rock layers and paleosols (buried soil horizons of the geologic past) consisting of indirect evidence of life by the movement, behavior and biological functions of organisms. Trace fossils may include scratch marks, tracks, trackways, trails, claw marks, burrows, tubes, borings, tunnels or tail drags resulting from activities and general movement of creatures that once lived in the environment where the sediment was deposited.
Trace fossils refer to any secondary evidence of life. This term does not include fossil remains nor does it include the impression of the original living organism. Trace fossils may be made from living things as small as microorganisms and as large as dinosaurs, by vertebrate or invertebrate animals in both marine and non-marine environments.
Trace fossils may also include the fossilized remains of excrements (coprolites), fecal pellets, regurgitation pellets, excavation pellets, nests, mud mounds, algal mounds, resting traces, locomotion traces (microorganism pathways, etc.), dwellings, feeding traces, traps, predation traces (small holes in shell fossils), teeth marks, root penetration structures and any markings on fossil bone caused by the trampling movement of vertebrate animals. Paleontologists analyze trace fossils in order to determine conditions of the environment in which the organisms lived and to study the life cycle and behavior of extinct species.
The "Definition of the Month" features words related to geology, paleontology, mining and desert history. Written by Steve Mulqueen for the VGMS, August 2005.
