The most commonly utilized clay types for pottery are earthenware, stoneware, and porcelain. Earthenware is widely used due to its ease of handling and low firing temperature, making it ideal for beginners. Stoneware is more durable and fired at higher temperatures, making it suitable for functional pottery like mugs and plates. Porcelain, known for its fine texture and translucency, is used for delicate and high-end ceramics. Other specialized clays, like ball clay and fire clay, are often mixed with primary clays to enhance their properties. The choice of clay depends on the desired finish, strength, and purpose of the pottery piece.
