 March 2017 Program  
                                                          Presented by: Dick Weber
 This month Dick Weber will introduce us to the colorful world of Fluorite. Due to a spectacular range of colors and well developed crystals, this mineral is highly sought after by collectors.  Clear and colorless when pure, fluorite can exhibit every color of the spectrum from the deepest purple to bright oranges and reds.  In addition to its aesthetic and scientific value, fluorite is a critical industrial mineral used in the production of thousands of commercial products.  Dick Weber was first exposed to the fluorite deposits of the Mississippi Valley while working on his geology degree. Actively collecting specimens for the last 15 years, he will bring a display showcasing pieces from famous locales.

Handy Hints and Other Tidbits

Gold Fill:  a layer of gold backed with another metal.
Gold Plate:  placing a base metal, as copper, in a bath and sealing through electroplate.
Gold Leaf:  a sheeting of gold varying from 4-5 millionths of an inch.
Yellow Gold:  a jewelry metal, 53% gold, 25% silver and 22% copper.
Liquid Gold:  finely divided gold in vegetable oil for gilding ceramics.
24 karat Gold:  Pure gold. 
A karat is a unit used to give the percent of gold in a gold alloy. One karat = 1/24 gold
An interesting note:  A single ounce of gold can be stretched into a wire 50 miles long!

CARE FOR YOUR TOOLS: Tools won’t rust if you spray them with PAM or WD-40 then wipe with a dry cloth.

FLAT LAPPING TIP: After lapping flat stones, such as cut thundereggs, with 600 grit, wash them and leave under a heat lamp or 100-watt bulb for about 15 minutes.  When the stones are warm, polish them on a felt wheel with tin oxide.  By pre-heating, the polishing is almost instant. Otherwise, the felt wheel has to heat the stone before the polishing begins. 


“Behind the Scenes”
The Del-Air Board of Directors would like to recognize and thank the “behind the scenes” efforts put forth by members Michael Tschacher, Jeff Dengrove and Bob Backus for their diligent efforts in supplying our education outreach team with a countless amount of tumbled & polished stones that our team distributes to each and every one of the 2nd, 4th and 5th grade students at the many, many schools they visited this season. You are our true “Rock Stars” and your efforts are greatly appreciated.
