摘要

Improvements in the processes for giving a shiny metallic finish to glass or other smooth material, particularly plastics, essentially characterized by subjecting the surface, despulidated, degreased and specially prepared, to a reactive action of a spray jet, integrated by the joint spray, in a single beam, of two different baths, coming from different containers and projected by a single spray gun, the reaction of these baths to each other, precisely in the presence of the prepared surface of the piece, in the one that is, in the act, deposited a fine and uniform layer of silver, one of the projection baths comprising an aqueous solution of caustic potash and hydrazine sulphate, while the other bath contains a silver nitrate solution with adequate addition of ammonia (Machine-translation by Google Translate, not legally binding)
