Product guide
 
ISHIKAWALITE is a natural material consisting mainly of SiO2 (silica), a pale yellowish white sandy pumice stone (natural rhyolitic glass).
The main feature of ISHIKAWALITE is that its particles have countless air holes that produce a large surface area, making it scientifically stable and lightweight. It is attracting a great deal of attention for its suitability as a slag remover. In order to provide a stable supply of high-quality products, we carry out our manufacturing in a factory equipped with the latest technology and quality management system; it is there that all of the manufacturing processes, including washing, high-temperature drying, and sifting take place.
