<p>PURPOSE:To obtain a pocket heater capable of lasting heat generation with infrared rays emitted from a volcanic rock for a long time by rubbing the pocket heater, and keeping a constant temperature, by adding powder of the volcanic rock to a composition prepared by incorporating iron powder with active carbon and a chemical, etc. CONSTITUTION:Powder of a volcanic rock (igneous rock) in an amount of e.g. 5wt%, is added to a component (B) of active carbon, chemical, e.g. common salt, and water, etc. in a composition of the component (B) and iron as a component (A) to give the aimed chemical pocket heater. In use, the heater is rubbed to mix the components (A) with (B) to generate heat. In the step, the heat generation lasts for a long time with infrared rays emitted from the volcanic rock.</p> |
