There are several types of clay, each with unique properties and uses. The main types include earthenware, stoneware, and porcelain. Earthenware is porous and often used for pottery and tiles. Stoneware is denser and more durable, making it suitable for functional items like dishes. Porcelain is known for its fine texture and translucence, often used for high-quality tableware and decorative pieces. Clays can also be categorized by their mineral content. For example, kaolin is a pure white clay used in porcelain, while bentonite is a clay that expands when wet, often used in drilling and sealing applications. Understanding these types helps in selecting the right clay for specific projects.
