Fused Quartz Mirror Blank 20 inch diameter, 2.5 inches thick Front and Back Side
Mirror is actually 19.75 inches in diameter. Mirror surface is extremely rough and is the condition as it was removed from the kiln.
I am told the blank is about 40 years old. The plan is to grind it into an astronomical mirror, of course.
