Abstract
The pyrogen of the invention is formed by the compression of ferrosilicon powder and a mixture of ferric oxide powder and another lower order iron oxide powder. This pyrogen overcomes the weaknesses inherent in earlier pyrogens by dispensing with the use of peroxides. The scope of the invention also extends to the canister which holds the pyrogen. The pyrogen, which is positioned inside the canister's combustion chamber in such a way that it comes into contact with the top of said combustion chamber, is supported by a special ceramic thermal insulator which contains an ignition device comprising an ignition agent, which also incorporates an instant high temperature generating ignition material, and a match head chemical which projects out of a hole in the base cover of the canister. The bottom of the canister is covered by a bottom cap which can be freely removed or replaced as required. The canister, which enables the heating or cooking of whatever is placed inside it, is compact, safe and cheap.
