ANTIMONY

Antimony is a silver white metal, very hard and brittle. It has no characteristic crystallographic surfaces when sheared. Melting temperature is 1167°F and even when melted at or above that temperature it is not easy to get a homogeneous alloy with lead. As soon as the pour is started the rapid cooling causes an increasing amount of antimony to solidify while pouring. SPLASH!

Antimony is only available in chunks or dust & fines.
