3510.     To Solder Iron. Apply good tough brass (see No. 3358 (How to Make Brass)) with borax mixed with water to the consistence of cream. (See No. 3488 (Hard Soldering or Brazing).)

3511. Solder for Joining Steel

3511.    Solder for Joining Steel. This is better than the usual brass solder, for uniting cast-steel, etc., as it fuses at a lower temperature; and, being whiter in appearance, renders the seams less observable. Take 19 parts, by weight, fine silver; 1 part copper, and 2 parts brass; melt them under a coat of charcoal dust.
