Cosmological Cosmetics: During manufacture or handling, the surfaces of mirror blanks can acquire some scratches or chipping at the edge, neither of which will have any effect on your mirror because you will be grinding out scratches and beveling your edges anyway. Blanks deemed to have more than average cosmetic imperfections will be placed on our Discount Mirror Blanks page, saving you even more on your glass mirror blanks and mirror grinding tools. Clearance mirror blanks are tested for internal stresses too - all the blanks we sell will make a fine telescope mirror

For a complete mirror making KIT, with all abrasives, polishing compounds, pitch, and grinding tool included, please see our Buy Telescope Mirror Kits website for great prices on plate glass telescope mirror making kits.
