Heat-reflecting glass with a good resistance to acids and bases and a good visible light reflecting power.

摘要

The invention relates to a glass coated with a film of iron and chromium oxides, reflecting heat radiation. Such glasses additionally exhibit good resistance to bases and to acids and good properties of reflection of visible radiation if the contents of iron (x expressed in mu g/cm<2>) and of chromium (y expressed in mu g/cm<2>) of the film are such that: 0.54 x >/= y >/= 0.3 x and advantageously if: 16 - 0.75 x >/= y >/= 16 - 1.6 x Such glasses are employed in building.
