Volcanic stone, originating from volcanic eruptions, is a porous rock formed by the rapid cooling and solidification of magma. It features a rough surface with abundant air pores, making it lightweight and capable of floating on water. Volcanic stone comes in various colors such as red and black, each with its unique charm. Its properties, including high strength, thermal insulation, heat preservation, and corrosion resistance, make it widely used in construction materials, water filtration, soil improvement, environmental protection, and medical fields. As a building material, it is sturdy, durable, and decorative. In water treatment, its strong adsorption capacity purifies water quality. In agriculture, volcanic stone is rich in trace elements, beneficial to soil amendment. Furthermore, it enhances the natural beauty of home decor. Widely sourced, volcanic stone is found in places like Yunnan and Inner Mongolia in China. With its unique properties and diverse applications, volcanic stone has become a highly sought-after natural resource.
