Providing telescope mirror making kits in 4, 6, 8, 10, and 12 inch diameters. All mirror making kits include the glass mirror blank and all the grinding and polishing supplies needed to complete an excellent reflecting telescope mirror. Upon request we can supply telescope mirror making kits in less commonly made mirror sizes of 5, 7, 9, 11, 13, and 14 inches.

All telescope mirror grinding kits include one glass mirror blank, silicon carbide and aluminum oxide grinding abrasives, cerium oxide polishing compound, optical grade tempered burgundy pitch, and enough hexagonal ceramic tiles to make one mirror grinding tool. There has been extensive discussion on the merits of plate glass vs. borosilicate glass (Pyrex) for telescope mirrors over the years. Read what Sky and Telescope Magazine has to say about Plate Glass vs. Pyrex - we could not have said it better. The mirror blanks included in our grinding kits are high quality annealed plate glass, individually tested to be free of internal strain for a mirror that will perform beautifully for a lifetime.
