Abstract From the Canadian patent

An ignitable solid material includes molten-metal-producing materials as well , as other mateirals for retaining its shape when ignited. The molten-metalproducing materials may include a metal-producing reaction mixture for , example including a reaction mixture comprising a reducing agent and a metal compound powder. The other materials may include a binder and a heat-, retaining material, such as sand. The ingredients of the ignitable solid material may be pressed together and dried to produce a solid, machinable, heat-producing material (a heat block) that may be ormed in any of a variety of shapes.
