Brass (Solutions of any desired color)

Brass solutions of any desired color may be made by adding carbonate of zinc, in varying proportions, to the above solution. One part of zinc and two of copper carbonates will give a beautiful golden yellow brass, and should be used with an anode of the same color. If, however, the plater desires to match colors on repairing jobs, etc., he can get any desired color from this bath by varying his current; a strong current will deposit more zinc than copper, giving a paler color of brass in the deposit; and a weaker current will deposit more copper than zinc, giving a redder deposit. In this way most repair jobs can be matched in color, although it is better, when doing new work, to make your solution of the color desired, and use an anode of the same color, as by doing so you put the two metals into the solution in the same proportion as you are taking them out. If you are using copper anodes, it is best to buy the electrically deposited anodes from a dealer in platers' supplies, as they cost no more, are always pure, and deposit much freer and smoother than the hard rolled copper for sale at metal houses. The same thing also applies to anodes of brass, gold or silver, but in less degree.
