Beeswax
Beeswax. A type of wax noted for its ductile yet hard qualities. It can be carved and cut at room temperatures, or can be melted and cast, then worked on again. When mixed with clays it can form a soft modeling material, it is a component of plasticine. At normal temperature beeswax is used by medallic companies to make an intermediate reduction on a pantograph. It is also used as an acid resistant material in acid etching. See wax.
