PRESIDENT'S MESSAGI!

Our spqheW dinner, combined with the October meeting, was a ptIa& IUCCCIS, It was attended by 130 members and ....... All 1IIUIl. Arnold Barron and his hard·warl<ina crew IerVed a wry and generous spread of spaghetti, s:a1ad, garlic broad. sherbet, and cookies. Joe Hammond had his interesting silene auction; members see up their swap and sell and our shop committee sold a table full of slabs. Elmer Snyder showed a display of the thank-you letters he has rece.ived from schools where he has presented a rock show. It is wonderful to read these spontaneous and sincere letters from youngsters.

The business portion of lhe evening was short; the main item was the report of the nominating committee. The nominees are listed elsewhere in this Petrograph, The election will be held at our November meeting and further nominations can be made from the floor at that lime. Please come to support and vote for the candidates of your choice.

Our shop committee continues to improve and add to the lapidary ~uir"""- ' ~~ " r!'ws. The shop is open at some time of the day or evening all seven days of the week , We invite you to check the schedule. call a friend and come over to join us. You might even start a project to enter in competition at our March show. Let's show other rockhounders what we can do.

Howard Buschke, President

MEMBERSHIP DRIVE

Yes, it is that time again. All dues will be expiring as of December 31.1991. You will find the 1992 membership application in this month's Petrograph. If possible, please mail in your dues with a stamped, self·addressed envelope. It does expedite the process a lot and is much appreciated. Also, since there is such a large volume of checks and membership applications to process at the beginning of each year, it is so much better if you mail them to me direcUy 10 process.

Again, I ask your patience in filling out new Conns each year. I have gotten a couple of complaints. but this small amount of paperwork on your end enables me to have a hanl copy with which to check all of my inputting of data afler all of the new information is added for Ihe new year. I actually compare names, addresSI.:s, and telephone numbers of all members. You will b.! surprised at how many changes in addresses have bllen made without notifying the Cluh. If th is was not updated, members would not get their newsletters, as third class mail is not forwarded. Again, please bear with me. I do need these applications fi lled out, and I will be just delaying your membership by sel lding you a letter antI application if I do not receive one iRitially.

Please do not forget to put down your area code wbeD you put down your pbone number. Due to the changes in the Bay Area area codes, it will be essential for roster infonnation and tel keep aU flJes current.

I appreciate your cooperation with the applications. This makes my job a heck of a lot easier. If you can, please renew early.

ATIENTION, FACETING INSTRUCTORS

We are in dire need of faceting instructors!!1 Those of you who have taken faceting lessons at our shop and have cut at least Wee stones are capable of teaching the basics of faceting. We have quite a waiting list and only two instructors. We are asking only that you teach the "Sweet Sixteen" for a couple of classes. If you have enjoyed faceting and would like to give back what you have learned, pleases volunteer to instruct Ie doesn't have to be forever, maybe just a couple of classes. Give the enjoyment you are geuing out of faceting to at least four more people.

ShopTalk

There has been a new piece of equipment added to our shop that I think ia exciting, a diamond band saw!! With this saw you can cut circles, curves and fancy designs. Be sure you . checked out on the saw before you use it. The saw was purchased with money from the special shop fund. This money we have collected from rock auctions and sales.

A group of us have brought to the shop three collections of rock that we arc selling in slabs and rough at the shop. We will also bring some to the November General meeting. There is aome real good material in these collections. So if you are a neW member or a veteran member you will find material at bargajn prices. Profits gocs to the shop special fund for more goodies.

What I really need arc members that would be willing to come and learn to run the saws. If you are interested call me at 538· 6254 or come by the shop on Sundays.

For those of you that usc the diamond grinding wheels remember to use a fmn pressure across the whole width of the wheel 80 they will wear evenly. There is a wheel in the back row for grinding large stones only. Cabs on the front wheels please!l! I am told the retail price for the type of wheels we use ia about $300.00 now.

Arnold Bmon - Shop Foreman

ARE YOU SURE IT IS JADE? (Color Country Chips)

) If a chip is knocked off the end of a suspected rock, the freshly broken swface should not sparkle in the suo. If it docs. it is not jade. If you can scratch it with a knife pint, it is not jade, It should be much heavier than a cornmon rock of similar size. Tap specimen lightly with a point of hammer. If a small moon-shaped fracture shows up. it is agate or jasper I but not jade. If it is jade, it will have a smooth, waxy, almost greasy look, Only positive test for Jade is x-ray analysis and specific gravity teslS.

APACHE TEARS (Hy Grader)

Many years ago in what is now our Western States. there were violent upheavals within the earth. Magma boiled and seethed below the surface and, in some areas, forced its way upward to spill out of volcanos and fISSures. Any of the liquid magma which reached the surface is called 1m: lava which cooled so quickly it did not have time 10 crystalize is called obsidian or volcanic glasa.

In weathering, especially where water gOl into cracks or crevices, this natural glass contracted and fractured inlO little curved scales, much like layers in pearls. This new rock. called ~t erodes away, 1eavinS rounded black nodules of the oriSinal obsidian -- Apache Tears. The proper name for them is Merekanite. Most people who arc unacquainted with Apache Tears are amazed to learn that liSht can be seen throuSh them. This is not due to the minerals involved as much as to their structure. Apache Tears are never found east of the Mississippi Rivet, only in the Wesl.

SHOP SUGGESTIONS (SMS Malrix)

For a lubricant in slab and trim saws, radiator anu-freeze can be used as a coolinS agenl. It has no odor, and will not rust your 88W or evapcntc. In addiUon, it lubricates well and being very soluble in water, is easier to clean from the rocks and your hands.

Spic and Span has oxalic acid in it and is especially Sood in po1ishinS mixtures.

- 11-

SHQP HINTS (Rock Licker)

To clean fragile crystals or hard-Io-reach recesses in mineral specimens. try "Crew", a product of Johnson's Wax. Spray on this foam, let stand a minute, then rinse with water. It is safe on aU minerals, including calcite and fluorite.

To polish stones and silver together, as in channel work, use cerium oxide. Other polishes may scratch the silver.

To stretch the life of your sawblades, rub a little beeswax or parafm into the teeth before and during your sawing. It doesn't take much, but it sure helps. Blades should last twice as long.

WORKING WITH BRUNEAU JASPER (East Bay Nodule)

Bruneau Jasper can be overheated in the sanding process, causing "burned" areas. These areas can be removed by sanding them very carefully and lightly using 10lS of water, and taking precautions to avoid overheating them again. One of the resullS of the burned areas is the development of minute pilS which have to be carefully sanded out of the stone.

Diamond "Nova" wheels work very weU to remove burned spotS and small pilS. The Nova wheels are slow, but there win be no danger of overheating, and the final result can be wonh the extra time required to get the desired result.

SHOP HINT (p<gmatito)

Whenever you slab banded agate. be ~, the lookout fa "iris", which wiD Dash pale blue, green, or pink in the clear bands. Always check the slab liainsl clear a sunlight, Fluorescent light tends to mask it. It is rare, but when you rmd it, it wiD "make yolD' day",

There is another way of finishing soapstone that we have heard of that the Chinese use or used. Heat the fmished article in an oven for one hour at 200Of', Remove from oven and apply a coat of paste wax. A jade effect resuilS from this method.

Silversmiths: Draw your jeweler's saw blade through an old candle, It coats the blade and you can saw faster. Wipe a piece of chalk: over yourjeweler's files. It keeps

mew slivers from clogging the file, and you can bLow them out.

CHRYSOCOLLA HINT (GEM-N-I)

To enhance the blue and green of chrysocoila, place it in a container of Purex fer as long as necessary.

TO PRESERVE A NEWSPAPER CLIPPING (pegmatite)

Dissolve a milk of magnesia tablet in a quart of club soda overnight. Pour into a pan large enough t accommodate the flattened newspaper. Soak clipping for an hour, remove, and pat dry. Estimated life: 200 years.

WORKING VARISCITE (Chip')

Variscite is a rare material and can be used in any type of jewelry that tutqooise is used. Most variscite is slighUy softer than lW'quoise but takes a good polish, except in the tumbler.

The larger matrix pieces can be slabbed with your regular saw, running in oil. Put the slabs in KiUy LiUCr ovemight to remove the oil, then wash in detergent. (Keep a container fUil of liner near the saw; it can be U8Cd for years. If it does become oil soaked, just spread it out on a newspaper in the sun for a few hours.)

The small, solid green nodules should be handled just like turquoise. Use a thin blade with water and detergent. This material can be backed with plastic steel and cut thin, if you wish. Being soft, it grinds fast, and afier sanding, will polish on almost anything. Sometimes yellow cr white rouge will bring out a real shine.

Since this is a rre material, do not waste it. Save all the small scraps and use them for inlay. It works beautifully when inlaid in channel with plastic steel like turquoise. Scraps can be placed in a mold with epoxies to make interesting cabs.

Variscite is easy to drill and excellent for beads of all kinds, including heishi. if you want a tapered choker, cut a bunch of cores from a slab and drill holes in center of each one. String them on piano wire held in a saw frame to sand, taper, and polish, allowing them to spin slightly.

SHQP HINT (Rocky Review)

Cut an inner tube into small squares and mix with the last stage in your tumbler. The pieces of rubber stick to the sides of the tumbler and keep those lazy stones rolling.

RECENT DEVELQPMENT IN CARVING TOOLS (OEM·N·I)

A new tool for cutting hard materials, called "Identigrave", made by the Paragrave Co., is now available. It is a tiny air turbine much smaller than a Foredom or Dremel handpiece and uses an air hose instead of the heavier steel cable. It turns at 400,000 rpms and uses a 100 psi air source.

More infonnation can be obtained by calling the manufacturer at 1/800/62447IS, Monday through Friday.

TUMBLING NOTES (Rocky Review)

When you are tumbling agates, use Indian tumbling garnets as a medium. As the garnets are ground down by the silicon carbide grit, the small pieces of garnet that are removed become emery, as in emery paper. These add funber to the grinding action on the agates. The garnets can be used several limes for each step, similar to the other tumbler media you use ~~ such as plastic pellets cr ceramic cubes. Tumbling garnets are relatively inexpensive, $3 to S4 per pound, and when they are fmished, they make sparkling liulc gems themllClves. Use about 2-1/2 pounds of garnet per 12~pound tumbler load.

Another tip: During the tumbling process, shake the tumbler barrel and then open and pour off some of the water. This will get rid of the rock dust as the grit quickly selUes 10 the bottom of the barrel and is not lost. Replace the lost water and continue tumbling. Eliminating this dust helps remove the fine panicles and improves the grinding ability of )'Our slurry.

Back to Basica Number 1

Several of our memb e r s have asked questions about rocks they have been collecting. Fortunately we do have several knowledgable memb e r s , but some of us are bew i ldered when our "experts" get technical. So here is a back to basics lesson for novices,

Catego rizing rocks is not easy . First of all a rock is made up of at l east two minerals ( a chemical that always has the same properti es). Geologists separate on the basis of origin. Igneous rocks are formed when molten material cools. Obsidian, a volcanic rock is a good example.Cooling qui ckly gives it a glassy appoarance, while those that . cool slowly form crystals,

As magma cools, min e rals rich i n iron and magnesium are the fir st to form. Later cooling b~ings quartz and feldspars.

Another group of ro c ks are known as sedimentary, caused by the gradual erosion of material. Layers accumulate over a long period of time.Shal e and sandstone are examples. Sedimentary rocks can also be f ormed by clepositi6n of diss oveo minerals. Gypsum and r ock salt !Lre formed when the water f~om the diss ol ved so lution evaporates. Coal and limest or e are sedimentary roc k ~ that onC6 were living things.

Sed im en ta ry r oc ks a ~ e d ifficu l t to classify because the debris from preexi Gt ing rocks is variable and subject to much mi~ing. Texture and composition are elements used to separate t he grou ps .

Severa 1 ferc es can 'let on the nbove rockEI to form u new gr oup c~ lied nl e tamo rph jc or c hanged rocks . They are us ually very ha rd bs cau s o tleat pres s ure and chemical action has c hal rged t hem . 'r hej r I"I t',igill is often hard to trace.

WORKING V ARISCITE (CHIPS)

Variscite is a rare material and can be used in any type of jewelry that turquoise is used. Most variscite is slightly softer than turquoise, but takes a good polish, except in the tumbler.

The larger matrix pieces can be slabbed with your regular saw, running in oil. Put the slabs in Kitty Litter overnight to remove the oil, then wash in detergent. (Keep a container full of litter near the saw. It can , be used f<Y years. If it does become oil soaked, just spread it out on a newspaper in the sun for a few hours.)

The small, solid green nodules should be handled just like turquoise. Use a thin blade with water and detergent. This material can be backed with plastic steel and cut thin, if you wish. Being soft, it grinds fast, and after sanding, will polish on almost anything. Sometimes yellow <Y white rouge will bring out a real shine.

Since this is a rare material, don't waste it Save all the small scraps and use them for inlay. It works beautifully when inlaid in channel with plastic steel like turquoise. Scraps can be placed in a mold with epoxies to make interesting cabs.

Variscite is easy to drill and excellent for beads of all kinds, including heishi. If you want a tapered choker, cut a bunch of cores from a slab and drill holes in center of each one. String them on piano wire held in a saw frame to sand, taper and polish, allowing them to spin slightly.

MEASURING AN OUNCE OF GRIT (Mineralog)

Many tumbling instructions teU you how much grit <Y polish to use per pound or rock, and this is usually in ounces. If you do not have an ounce scale handy, the following table can be used.

Course Grit: 1 oz = 4 level teaspoons Medium Grit: 1 ox = 4 level teaspoons Fine Grit: 1 ox = 4 leel teaspoons Polish Powder: 1 ox = 8 level teaspoons

A SIMPLE EXPLANATION OF THE LOST WAX PROCESS (pegmatite)

A wax pattern is made in the exact size and form of the item to be cast. The pattern can be all wa)(, or it can incorporate materials that will bum out completely.

A sprue is attached at one or more places. The sprue looks like a handle and is usually about 1/8" thick for an average size ring. It may have a funnel shape to its end, to guide the molten metal during casting.

The flask holds the wax pattern while it is invested. It resembles a tin can without a top or bottom.

The investment is a powder mixed with water that sets up like Plaster of Paris.

The bum-out melts the wax and bums out everything combustible, leaving a cavity within the investment, the exact size and fonn of the pattern, hence the term "Lost Wax".

The metal is heated with a torch until it melts, then it is forced into the cavity by centrifugal, steam, or a vacuum device, where the metal rapidly solidifies. The hot flask is put into water and the shock disintegrates the investment, freezing the model.

The metal model has its sprues removed, is fmished, gems (if any) are set, and the jewelry is ready to wear.

PETRIFIED WOOD? (Mineralog)

"Petrified wood" is really a misnomner, for wood is actually agatized, jasperized, or opalized. In other words, during the many years of burial, the wood has been replaced, cell by cell, generally by a silica material. The general structure of the wood remains discemable, including the concentric rings of growth, the microscopic cellular structure of the wood, and often the structure of the bark. No wood remains, it has been entirely replaced by mineral material.

Limb casts are distinguished from petrified wood by the complete absence of any structural appearances, no ceUs, or growth rings, it has been completely replaced by agate or chalcedony, generally retaining the form (or mold) of the limb of the tnmk.
