Frosting Brass

A very fine ornamental finish, resembling brushed work, may be applied to brass articles by boiling them in a caustic-potash solution, then rinsing in clear water, whereupon they are dipped into dilute nitric acid until the oxide is removed, then rinsed quickly and dried in sawdust. The surface should be lacquered while the metal is hot.
