Kaolin Ball clay-139 is highly plastic clay used in ceramics, especially for making porcelain and fine ceramics. Its plasticity allows it to retain shape when fired at high temperatures. It's mined from deep deposits, processed to remove impurities, and often blended with other clays for specific properties.

Potassium feldspar, another common feldspar mineral, is also found in igneous rocks. Its chemical formula is (K,Na)AlSi3O8, with potassium and sometimes sodium. It shares similar industrial uses with sodium feldspar, like ceramics and glass production. Varieties include orthoclase and microcline. Potassium feldspar is a vital component in many rocks and has various industrial applications.

Sodium feldspar is a common mineral found in igneous rocks. It has a chemical formula of (Na,K)AlSi3O8, containing sodium and sometimes potassium. It is used in ceramics and glass manufacturing due to its color and chemical properties. Varieties include albite and oligoclase. Sodium feldspar is a key component of many rocks and is valuable in various industries.

Kaolin Clay-138 is a white or colored clay mineral primarily used in ceramics, paper, paint, and cosmetics. It's known for its absorbent properties and is used medically to treat diarrhea. It's abundant worldwide and often refined for various applications.
