Brass for Solder

Melt together 12 parts fine yellow brass (see No. 3359), 6 parts zinc, and 1 part tin. Used for ordinary brazing. cle, as far as it is to be frosted, in the mixture for a short time; then immerse it, so as just to cover it, in sour beer, and scour it under the beer with a brush made of fine brass wire (a scratch brush); wash it in water, and afterwards in alcohol. The surface is then ready to gild or silver-plate if desired.
