Page 1 of 4 fused silica primary 6 gregorian posted in atm, optics and diy forum: at stellafane this weekend i managed to score a 6 fused silica (quartz) disk about 1 thick. i dont think it was originally intended as a mirror blank, as it tapers by about 0.5 on the back side. it had duct tape on the back when i got it, as well as strange strips of adhesive stuff that is somewhat.
