[Prior art]
Otani stone was formed by burying volcanic ash erupted in the activity of submarine volcanoes in seawater about 2000 years ago. It is said to be a rhyolitic welded tuff in geological petrology. Is a silicate (zeolite), specifically composed of a large amount of pumiceous glass and feldspar, and a small amount of biotite, amphibolite, pyroxene, etc. The physical properties are porous and excellent in fire resistance, earthquake resistance, and moisture resistance In addition, because of its adsorption and deodorizing effects, it has been conventionally used mainly for construction materials and civil engineering materials.
[0003]
However, in recent years, thin stone materials have been produced due to the development of the stone laying method for Otani stone, the development of adhesives and mortar admixtures, and the emergence of weathering inhibitors, etc., and the use as decorative materials has expanded. In fact, a bathtub made of Otani stone has not been developed yet.
