Fur a liquid solution for gilding brass and bronze, dissolve 1/4oz. of gold chloride in 5 qt. of distilled water: then add 2) 11). of caustic potash, ooz. of pearlash, and 2oz. of cyanide of potassium, and stir until all is dissolved. Dip the articles in this solution whilst at a nearly boiling temperature. The colour of the gilding will be affected by the temperature of the solution, and it may be necessary afterwards to work up the surface with a brush. A solution for gilding silver and German silver may be made by dissolving 20 grains of gold chloride in 1 pt. of distilled water, then adding gradually 1 1/2oz. of acid carbonate of potassium. Mix this with another solution containing l 1/2oz. of acid carbonate of potassium in 1 qt. of water, and boil the mixture until it turns green, when it is ready for use. Silver articles to be gilded in this solution must be attached to thin strips of zinc. Gilding by this process may be made more permanent by first thinly coating the articles with mercury in a solution of nitrate of mercury.
