August 2013 Program

PROGRAM Topic: “Quartz” by Scott Gregory.

Who knew there were so many different varieties of quartz?

What is the difference between silicon, silica, silicates and silicone?

Scott displayed two tables of quartz varieties and provided an 18 page handout for all to take home.

He covered macrocrystalline quartz (all the colored varieties like amethyst), cryptocrystalline quartz like agate, and amorphous quartz like opal.

Scott identified all kinds of fun facts such as: heat quartz to 350 degrees and it may change color.

Thanks, Scott!
