This is a process for imitating on metal, plaster, wood or other material, the peculiar appearance produced by chemical action upon the surface of bronze metal. It is accomplished by spreading over the surface of the material to be ornamented a very thin coating of bronze-powder, which is caused to adhere either by applying it directly upon a coating of any of the sizes mentioned in the foregoing pages, or by mixing with a vehicle, such as gum-Arabic or transparent varnish. The latter is most desirable, as in the other case, being subject to the direct action of the atmosphere, the bronze-powder soon tarnishes. In ornamenting furniture, bronzing is generally employed to represent gilding, a variety of bronze called gold-bronze being used, which affords an excellent imitation but is not very lasting. It is usually applied after the completion of the other finishing processes, the ground-work being prepared in the manner described under Oil-Gilding, and the size likewise applied as there described. A small wad of cotton-batting is then dipped in the bronze and passed gently over the sized portions, causing the bronze to adhere. In the other method - that of applying the bronze by means of a vehicle-the preliminaries of whiting the ground and sizing are not necessary, a small quantity of bronze being simply mixed with the vehicle employed to such a degree of fluidity that it will flow easily, and in that condition applied with a fine brush. Many preparations are used as vehicles, such as transparent varnish thinned with turpentine, gum-Arabic dissolved in water, and gold-size reduced with parchment-size. There are a variety of colors in bronze-powders, and to produce the best effect the size or vehicle should be of a color similar to that of the bronze used; in gold-size the coloring pigment is ochre, and in its place, for green-bronze, red-bronze, or blue-bronze, may be employed respectively verditer, vermillion or Prussian blue, a very small quantity being sufficient. In bronzing on painted work the ground should be as nearly as possible the color of the bronze to be applied.
