..I still haven't totally forgot about producing my own mirror blanks, in a kiln with a good annealing program.


A part-article flash-back from Astronomy Magazine Nov/98' "Astronomy's Archangel"

"Telescope innovator Roger Angel spins out new ideas the way the Arizona desert produces dust devils on a hot afternoon. He once dreamt up an ingeneous x-ray telescope based on the matrix of square, light-gathering cells of the lobster's eye.
He obtained glass pans (a new, flame resistant style of Corning called Vision) from a Tucson bank,in exchange for opening an account. He melted the Pyrex dishes in a small potter's kiln in an experiment which showed that borosilicate glass can be melted in telescope mirror molds bigger than back-yard swimming pools. (With his cookware discovery, and a vision he shared with Arizona colleague Neville Woolf, he founded the renowned Mirror Laboratory at the University of Arizona."
