Bronzing

Bronzing, the process by which a bronze-like surface is given to an object, which may or may not be of metal. In the case of metals this is usually done by rubbing with various solutions, as dilute nitric acid, sal ammoniac and vinegar, verdigris and vinegar, etc. Wooden and plaster objects are generally bronzed by washing with a solution of water glass (sodium silicate), dusting on a bronze powder, shaking off the excess, and drying.
