For gilding small goods by the electro process, place a pint of distilled water in an enamelled iron saucepan and dissolve therein loz. of best potassium cyanide. Heat this to 160° F. on a gas stove. Get two strips of pure gold and two lengths of No. 22 copper wire, and suspend the gold strips by the wires in the hot cyanide solution • then connect the wires to the battery and allow a full current to pass through the solution, from one gold strip to the other, for about two hours. Then take off that gold strip which is attached to the wire from the zinc of the battery, and substitute a strip of clean German silver. If this takes on a good coat of gold in a few seconds, the solution is in working order, and the two gold strips may then be both attached to the wire from the silver, copper, or carbon of the battery and used as anodes. If the coating is not satisfactory, dissolve some more of the gold as at first, until the solution will gild well. The same solution may be made at once by the direct process - that is, by dissolving 1/2oz. of gold cyanide in the hot cyanide of potassium solution.

These gold solutions give good results when worked at a temperature of from 140° to 160' F., and will give a good coat of gold with current from one Smee cell when an anode (or dissolving plate) of pure gold is employed.
