Properties of Clay

• Clay has several properties that make it useful for a variety of purposes:
• Plasticity: Clay can be molded and shaped into a variety of forms, making it useful for pottery and sculpture.
• Adhesion: Clay particles have a tendency to stick together, which makes it useful for construction and as a binding agent.
• Absorption: Certain types of clay, such as bentonite, are highly absorbent and can be used to absorb liquids or oils.
• Porosity: Clay is porous, which makes it useful for water filtration and as a natural building material.

Uses of Clay

• Clay has a wide range of uses, including:
• Pottery and ceramics: Clay has been used for thousands of years to make pottery and ceramics, such as bowls, vases, and figurines.
• Construction: Clay is used as a natural building material, such as in the construction of adobe houses.
• Cosmetics and skincare: Certain types of clay, such as bentonite, are used in cosmetics and skincare products to absorb excess oil and impurities from the skin.
