Volcanic stone (commonly known as pumice or porous basalt) is a functional and environmentally friendly material, which is a very precious porous stone formed by volcanic glass, minerals, and bubbles after a volcanic eruption. Volcanic stone contains dozens of minerals and trace elements such as sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt, and molybdenum. It is non radiative and has far-infrared magnetic waves. After a merciless volcanic eruption, after tens of thousands of years, Humans are increasingly discovering its value. It has now expanded its application fields to fields such as architecture, water conservancy, grinding, filter materials, barbecue charcoal, landscaping, soilless cultivation, and ornamental products, playing an irreplaceable role in various industries.

Basalt is a kind of basic Volcanic rock, which is a kind of compact or foam structure rock formed by the magma from the volcano after cooling on the surface. It belongs to magmatic rock. Its rock structure often exhibits stomatal, almond like, and porphyritic structures, sometimes with large mineral crystals. Unweathered basalt is mainly black and gray, and there are also black brown, dark purple, and grayish green.

Porous basalt (pumice), due to its high porosity and considerable hardness, can be mixed with concrete to reduce its weight, but it is still strong and has characteristics such as sound insulation and heat insulation. It is a good aggregate for lightweight concrete in high-rise buildings. Pumice is still a good grinding material, which can be used to grind metal and stone materials; In industry, it can also be used as filters, dryers, catalysts, etc.Professional natural volcanic stone tiles lava and basalt stone for sale.
