る。This far-infrared ray is emitted from many substances in principle, but is usually far enough to be recognized as effective, and is generally emitted effectively from earthenware ceramics, which are also heated. Since far-infrared rays are a type of electromagnetic wave, when they hit a substance, they are reflected in the form of heat,
By causing phenomena such as permeation and absorption and moving inside the substance from a high-temperature portion to a low-temperature portion in the form of conduction heat and convection heat, ceramics, that is, ceramics, also have high heat storage properties.

ミックスの比表面積をより大きくする必要がある。When ceramics are heated by a primary heat source such as a gas burner, the ceramics are heated from the surface, and the inside thereof is gradually heated by heat conduction, so that the whole becomes high temperature and emits strong far infrared rays. In order to efficiently and rapidly absorb the heat from the primary heat source, it is necessary to increase the specific surface area of the ceramic.
