The main uses of basalt

There are many raw materials used as ceramic glaze. But it is not widely used in this area. Nowadays, it is mainly used as a raw material for building stone and cast stone. Basalt as a glaze for the production of ceramic products it has many advantages, and basalt is widely distributed in China can be used to add some of the auxiliary raw materials for the preparation of ceramic products glaze for different firing temperatures 

Basalt, a dense or foamy structured rock formed by the cooling and solidification of magma from a volcanic eruption. It is classified as a magmatic rock in the geological classification of rocks. The temperature of magma from volcanic eruptions is as high as 1,200 degrees Celsius, and because of its viscosity, when the terrain is gentle, the magma flows slowly, only a few meters per minute; when it encounters a steep slope, the speed is greatly accelerated. During the flow, it carries a lot of water vapor and bubbles, and after cooling, it forms various variant shapes. In the north of Mirror Lake, there are waterfall-like and wave-like; in the area of Yingge Ling, there are round bun-like and pagoda-like Between Bohai Town and Shalan Township, there are python-like and lava tunnels, etc. The geology and geomorphic structure of this place is Xinying and colorful.

The main components of basalt are silicon dioxide, aluminum trioxide, iron oxide, calcium oxide, magnesium oxide The content of silicon dioxide is the most, accounting for about forty-five to fifty percent

The color of basalt is usually black, black-brown or dark green. Because of its dense texture, its specific gravity is heavier than that of granite, limestone and shale.
