A suitable solder for use in brazing small steel articles may be made in the proportions of silver 18, brass wire 2, copper 1. Melt in a crucible; when cold, hammer into a thin sheet, or granulate while molten by pouring into water. For small articles, a solder that will flow at a lower temperature than brass wire should be used. To braze or solder the article, clean the parts to be united and coat with pulverised borax which has been previously heated; cut off a narrow strip of the solder, if in the sheet, and place on the parts to be united, then heat until the solder fuses. The solder should be used sparingly.
