Mineral constituents of rocks undergo substance reactions with oxygen and hydrogen to produce color. Most mineral pigments occur in rocks when they react with sunlight. Metals like silver, iron and gold are human-made substances that produce color when they react with light and other components. In the previous , the majority of mineral pigments were made in the process of weathering in the earth.

Bentonite (oba) is a clay made up of montmorillonite/bentonite / silica / gypsum / boron as well as alumina ). It usually forms inside water-logged soils from rains or by erosion from the hillsides and cliffs. That is now used as a water softener to areas with low elevations. Bentonite clay soil can be efficient in resisting salty conditions that include salty and saline lakes and rivers.

Salts from the clay can help in stabilizing bones and teeth during archaeological excavations, because they are usually insoluble within the mineral boron. The clay could also function as an organic fertilizer. Bentonite is a very popular mineral compound used as a compost is called bentonite. Other uses are as a fertiliser for gardens as well as a natural pesticide in addition to as an antimicrobial against fungus, insects, and mold.

As a mineral, bentonite is water-soluble and forms a gelatinous solution when mixed together with water. It is also soluble in ethylene dioxide (oil) in addition to non petroleum diesel. This gives it the possibility of functioning as a dispersant as well as an antiseptic. This is soluble in petroleum jelly, petroleum liquid in addition to talc. It will be impervious to acids, alkalis, solvents, surfactants, and most chemicals.

The advantages of using bentonite for soil amendment are numerous. One benefit is the mineral content, which is different from one source another. This specific variation makes bentonites a great alternative to synthetic man-made substances in any situation in which one prefers to use a natural product. Bentonite clay may be added to soil to act as a leaching agent for the creation of silica, as well as other valuable mineral varieties such as strontium as well as calcium, chromium and even potassium . It is a very good soil conditioner , which can lower acidity and alkalinity (precautions against acidic or basic water that could harm other types of non-mineralized soils ) and is an ideal alternative to Gypsum plaster to make attractive insulating and flooring materials. It is also an excellent sealant for household textiles and clothing.

A key characteristic of bentonite clay is its capacity to absorb charge that is negative. Its negative charge arises caused by that bentonite has pieces that comprise either an ionic non-ionic charge. This charge, which is nonionic in nature, is the main reason that bentonite clays do not expand, whereas vitamin salts do due to its presence. Water vapor.

Bentonite clays are made from humic shale, an sedimentary rock composed regarding iron and aluminum. A fine deposit of bentonite is found in typically the Black River (Korean) in addition to Switzerland. In addition to being used as a leaching medium for the production of silica , the clay is also used to make fine-grained clays which are that are suitable for plastering. It is known to possess properties of thermal superiority to marble and granite, making it suitable for thermal insulation flooring and other flooring. Due to its electrical insulating and thermal conductivity attributes , montmorillonite (also called black diamond) is definitely used extensively as a fire suppressant within electrical and thermal insulation components due to its extraordinary strength. It is extremely resistant to chemical and thermal resistance, and does not react with the majority of acids.
