Copper Paint for Cast-Iron.

The Manufacturer and builder 12, 1876

M. Andry, of Paris, France, who has been so successful in electro-plating with copper the cast-iron monumental fountains in the Place de la Concorde, makes his new copper paint from porous copper deposited by the galvanic battery, mixed with varnish. The solvent of this varnish is the light and refined petroleum, or what we call benzine. The copper deposited in a galvanic battery is very pure and easily pulverized; it is mixed with a benzine varnish, and may be applied either to iron, brass, plaster, or wood. When this copper is mixed with vegetable and oxidizable oils, it acquired a green antique hue.
