Coating non-metallic surfaces with metals.- A process for forming a metallic coating on cement-, gypsum-, trass-, or other mortar comprises mixing the cementitious material with finely-divided metal or ore, or both, and a liquid so as to form a mortar, and afterwards treating the surface of the hardened mortar with a solution of a salt, such as copper sulphate, whereby the metal of the salt is precipitated on the surface, or the metal in the mortar is replaced to a certain depth by the metal of the salt. Sand, stone, graphite, &c. may be added to the mortar materials, and the mortar before treatment with the salt solution may be made into blocks or may be applied to the surfaces of bricks, stone, &c.
