Humans have used quartz since prehistoric times and continue to the present. We use its crystal structure, fracture, piezoelectric energy, and asterism in present day technology.
During this presentation, Tom Piscitelli will consider: How did quartz help win WWI and WWII? How can you make music with quartz? How does quartz keep your watches and clocks ticking? Why is quartz at the heart of your radio, TV, and computer? How can it make you a star and keep you healthy?
You'll examine examples of quartz crystals from two famous major localities: Herkimer, NY and Mt. Ida, Arkansas and discover how and when these crystals formed. You'll also see geodes from Dugway, Utah and Oregon thunder-eggs, and learn how they were formed.
Tom will display many forms of quartz: chalcedony, flint, chert, jasper, agate, onyx, silicified or agatized petrified wood, opal, and obsidian. You'll see some surprisingly unique quartz forms.
