- Origin：
Green Clay, which belongs to silty mudstone, is a large category named after the appearance and color of mineral materials.
Because the green clay contains less iron and is mainly composed of iron ions, the mineral material basically presents green tones of different shades. Due to the high content of alumina and the light color of most of the green mud minerals, the surface is easily oxidized and discolored during the long-term contact with the air.
- Features:
The color of the green clay is similar to the skin of mung bean, and it is light grass green. It is produced in the Huanglong Mountain lode. The finished purple clay teapot is beige and blue, with a simple texture, fine sand and full of granular beauty. After soaking, it gradually turns into a warm and bright color. It has a good patina and is easy to soak.
There are many kinds of green clay mineral materials. According to the difference of the mining area and the mine layer, the green clay has a variety of different appearances and firing effects.
- Generally speaking, green clay can be divided into three categories: Blackish green clay, Benshan green clay and sesame green clay.
