Clay soil is a term that refers to sedimentary Rocks containing a significant amount of Clay minerals, such as rock. Iran is one of the special regions of the world that has many resources; The export capacity of clay from the waters of Chabahar port to Pakistan shows that Iran has the richest resources.

In general, clays are very soft mineral compounds with fine grains. Different clays have different solutes and compositions, and as a result, different properties. In fact, clays are formed as a result of the erosion of rocks exposed to water and weather over time. Different types of clay with unique properties are very effective in cleaning and strengthening the skin. For centuries, clays have been used in beauty products, especially face masks, and today they are more popular than ever. Different clays have different properties, but their general properties and performance are based on absorption and ion exchange capacity. While using various types of clay in cosmetic products, including clay face masks, these materials clean the skin pores and exfoliate by absorbing fats and impurities. Also, by increasing the blood flow, they help to make the skin clear and fresh.

Clay is formed from the long-term erosion of Minerals and contains large amounts of silicon and Aluminum in its composition. This soil is formed from the weathering of rocks such as Granite and feldspar, it has very small grains that create high adhesion when combined with water. The structural components of this soil consist of four layers and include different types such as kaolinite and refractory soil, normal clay or bentonite clay. Clay has many applications in plant breeding, Steel industry, medicine and especially construction.
