I have been offered a fused quartz blank, 14.5 inches by 1 inch thick. I have never used this stuff before though I have heard of it. Anyone here have any experience with this material? How does it compare with Pyrex or Plate? My cost is one f4.5 tool. Comments? David Davis Toledo, OR 97391 _______________________________________________ ATM mailing list http://www.atmlist.net/
