Pour the antimony into the tin, then mix with the copper away from the fire in a separate pot. In melting the composition, it is better to keep a small quantity of powdered charcoal on the surface of the metal. The above composition is called "hardening." For lining-metal, take 1 lb. of hardening and melt it with 2 lb. of tin, which produces the lining-metal for use.
