A dwindling number of domestic suppliers of fire-resistant wax stone! This is the ore mined by our company.
Tobashi Mining Co., Ltd. conducts "underground mining," extending tunnels deep underground to extract the desired ore, providing high-quality and stable natural raw materials. "Wax stone (pyrophyllite)" is utilized in the production of firebricks, taking advantage of its high refractoriness, and remains a key industry in Bizen City. It is shipped as materials for blast furnaces and various furnace materials in steelworks and refineries, as well as for incinerators and heat-resistant components. As one of the few domestic suppliers of wax stone for refractory applications, our company continues to supply it. [Features] - The production of firebricks utilizing the high refractoriness of wax stone remains a key industry in Bizen City. - Shipped as materials for blast furnaces and various furnace materials in steelworks and refineries, as well as for incinerators and heat-resistant components. - The majority of wax stone currently used in Bizen City is raw material imported from overseas. - The use of domestic wax stone has significantly decreased. - Many of our wax stones are shipped as raw materials for wax stone clay. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【What is Soapstone (Pyrophyllite Type)】 ■ It has a white, translucent appearance similar to that of a candle and a slippery texture when touched (commonly referred to as "waxy feel"). ■ It is very brittle and tends to break along the stone's cleavage planes. ■ When viewed up close, it appears somewhat grayish-white, but from a distance, it can generally look blue. ■ It is almost indistinguishable from ceramic stone, but it differs in texture, color, and how it breaks. ■ Not only are there differences in appearance and texture, but there are also significant differences in usage and properties. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Tsuchihashi Mining Co., Ltd. is one of the few mines in Japan that produces high-quality sericite (silk mica). Sericite is mainly used as a material for ceramics. We also mine steatite (pyrophyllite) which is used as a raw material for refractory bricks and glazes, as well as high-purity silica (silica). Please feel free to consult us if you have any requests.
