Abstract

Procedure for the improvement of the surface of objects of hardenable synthetic material, obtainable in a mold, according to which the objects, in a state yet not hardened, with contact with an improvement agent, first applying on the inner wall of the mold a layer of uniform thickness of a powder consisting substantially of a metal or dye, as well as a binder, preferably a curable synthetic material, the powder being then sintered and the object still not cured being deposited directly on the powder layer, so that it hardens together with it, characterized in that the coating formed by the powder layer on the object is additionally covered with a metal or respectively varnish layer.
