In preparing this for the trade, for jobbers' or dealers' shelves, the manufacturer must take especial care to select the very finest gold bronze, nothing coarser than that known as No. 6000 will do; also see that the liquid does not contain any turpentine or rosin spirit, as that would tend to green off the bronze very rapidly. A varnish that contains appreciable portions of oil will not serve the purpose, as it will dull the luster of the bronze. A very good formula for gold paint is as follows: Melt hardened rosin in a kettle and pour the melt on a flat pan to cool. When it has become hard, powder it by running through a drug or spice mill or crush in a mortar, then dissolve it, in the cold way, in any hydrocarbon, whose boiling point is below 300°F. Ordinary 62 ° benzine, that is treated with five per cent of its weight of caustic lime in powder by agitation and then clarified by Alteration has given the best results. Ten pounds of the remelted and powdered hardened rosin to ninety pounds of benzine will make the best liquid for gold paint. Forty pounds fine gold bronze to 100 pounds of the liquid will produce close to 18 gallons liquid gold bronze.
