<p>PROBLEM TO BE SOLVED: To make a far-infrared rays irradiating element more efficiently manifest an effect of electromagnetic waves of the far-infrared rays irradiated through the surface of a vessel made of pottery by blending the far-infrared rays irradiating element into a glaze. SOLUTION: This vessel made of pottery has a glaze blended with 1-20 wt.% in an external adding ratio of tuffaceous sandstone having 1-60μm granule diameter on the inside surface of the main body. The tuffaceous sandstone contains SiO2 , Al2 O3 , Fe2 O3 , TiO2 , CaO, MgO, Na2 O, K2 O and MnO.</p> |
