need some facts about quartz?
Optical flats, radio crystals, lenses, lab ware (fused quartz), jewelry, piezoelectric devices, filter frits, abrasives, halogen lamps, optical fiber for telecommunications, telescope mirrors.
Quartz is used in jewelry, watch parts, counter tops (like kitchen counters ), sandpaper... That's all I've got! :) hope it helps!
