A process for making semi-reflective metallized glasses containing an anchoring layer, said anchoring layer being deposited by vacuum evaporation from an alloy comprising nickel in an amount of from about 40-70% by weight, chromium in an amount of from about 5-31% by weight, and molybdenum in an amount of from about 3-28% by weight. The anchoring layer may also be deposited from an alloy of nickel, chromium, molybdenum and at least one metal selected from the group of tungsten, iron and cobalt, in an amount of from about 55-75% by weight nickel, iron and cobalt, from about 5-31% by weight chromium, and from about 3-28% by weight molybdenum and tungsten. The anchoring layer is deposited upon the surface of a support glass by vacuum evaporation after which one or more layers may be deposited upon this anchoring layer.
