ROCKWOOD ROCKHOUND NEWS for DECEMBER 2000

Christmas Party
This year The Toenjes have graciously offered their home for the Christmas party. The club will furnish the meat while members will sign up to bring either a salad, vegetable or dessert. If you aren't already signed up, please call Claudia at 314-434-4831 to let us know what you are bringing.
For the gift exchange, we thought it might be fun if each of us wrapped a rock to trade.
The Toenjes home is quite easy to get to as it is near the Daniel Boone Library.
Once on Clarkson, turn east on Marsh. Go. 12 miles to Hill Top and turn left. Take Hill Top for .16mi.
Then turn right onto Fairview Drive.


COMMENTS, ETC
We have had some difficulty getting together a nominating committee, therefore, we do not have a new slate of officers for our next calendar year. It was decided at the November meeting to keep the officers we have until 2001. We really need to show our appreciation for the willingness of these people to continue serving year after year. So next time we see Bob Morse, Peggy Nuske, Helen Heitland and Andy Larson, Give them a pat on the back and a big thank you!

Dues are due again. They are $15 for singles and $20 for a family.


Happiness Is---
Licking a dirty rock and finding bands - 
Finding a gavel road paved with geodes - 
A husband and wife both "Rockhounds" -
Having the rain stop when you get to tile mine -
Meeting someone who is also interested in rocks - 
Your first field trip after a long winter!

I've looked into Pough's and memorized Moh's
And even paid Dana a visit;
But when it's all said, I still scratch my head
And sit there and wonder - - What is it?

HINTS & TIPS...
To use your silver or gold scrap, take an old straw broom, wet it thoroughly, and pour your melted scrap down among the straws. The result will be a beautiful broom-straw pendant.
If you like nuggets of silver or gold, take some more scrap and a small pan. Place some rock salt in the bottom, pour your melted scrap over the salt, and as the salt melts, there will be indentations similar to natural nuggets.

The color of money.
A .90ct green diamond sold at auction last fall to a private collector for a whopping $600,000, making it a record $670,000/carat -- the highest per-carat price ever paid for a natural green diamond.

HOW SILICON CHIPS ARE MADE -- How does silicon dioxide [beach sand] become an integrated circuit, one of man's most intricate and finely crafted devices?
Growing silicon crystals from a single seed crystal is the most important part of the process. This takes place in a furnace which is heated to about 1,5000 degrees Celsius. In the furnace is a container filled with molten silicon and a secondary element such as phosphorus or boron. The seed crystal is dipped into the molten material; it is then withdrawn with a rotating motion, similar to making candles by dipping them in hot wax.
Solidifying on the seed, the molten material takes on the same atomic structure as the seed. This molecular symmetry distinguishes a single crystal from unstructured or non-symmetrical material. Each finished crystal cylinder is approximately six inches in diameter and about four feet long. Using a high speed diamond edged saw, the cooled glass-like cylinder is the sliced into wafers. All silicon wafers are not the same, each manufacturer's wafer varies in thickness and surface finish due to their unique specifications.
It takes about 50 complex steps to convert wafers into integrated circuits. The final step is cutting the wafer into hundreds of tiny circuit chips.
