Here are instructions on bronzing a Cordelova (imitation plaster) lrieze. Apply to the frieze two coats of oil paint. For the bronze colour, mix in oil 1/2 lb. of burnt umber, 1/2 lb. of Brunswick green, and add Venetian red until a good bronze colour is obtained. A penny that has been in circulation for a year or two may be used as a colour test. Thin the colour with half varnish and half boiled oil, and give the frieze a good coat. On the following day, while the frieze is still tacky, apply bronze powder (copper, silver, or gold) to the parts of the frieze in relief. A paper-hanger's roller covered with plush can be used for this purpose. Run the plush-covered roller through the bronze and then over the parts of the frieze that are in relief. A white coat brushed over with knotting thinned with methylated spirit gives a good imitation of old ivory.
