_Rule for making._—Take 100 lbs. good old lead or lead cuttings, run it
down thoroughly, stir it up and take off all dirt or dross: then take
50 lbs. pure tin, let this run down, and when nearly all is melted and
is a little cooler throw in 1/2 lb. of black rosin, and well stir the
lot up. Last bring up the heat to 600 degrees which may be known by the
burning of a bit of newspaper put in the pot. The solder is now hot
enough and should be well stirred and then run into moulds.
