    Patent number: 4750827
    Abstract: Processes for manufacturing substrates of mirrors of resin concrete and the corresponding mirrors. A process for manufacturing a mirror substrate including the following operations: (1) a mould is manufactured of which the bottom has a polished upper face, complementary of the reflecting face to be made; (2) the polished face is coated with a film of a demoulding product and a hard, uniform layer is deposited; and (3) a resin concrete is cast into the mould and it is left to harden and then demoulding is effected in order to obtain a substrate of resin concrete.
