What kind of clay is typically used for high-temperature firing and creates a fine finish?

Porcelain is recognized for its exceptional qualities that make it ideal for high-temperature firing. This type of clay is composed of kaolin, feldspar, and quartz, allowing it to withstand high temperatures while achieving a very smooth, fine finish. When fired at these elevated temperatures, which typically range from about 1,200°C to 1,400°C (2,192°F to 2,552°F), porcelain transforms into a strong, dense, and often translucent material, which is highly valued in ceramics for its beauty and durability.

The high firing temperature not only enhances its strength but also reduces porosity, making porcelain less likely to absorb moisture and stains compared to other types of clay. Additionally, porcelain can be beautifully glazed, further enhancing its finish and making it suitable for both functional and decorative pieces.

Other types of clay, such as earthenware and stoneware, do not reach the same firing temperatures as porcelain and typically have different textural and aesthetic qualities. Earthenware tends to be more coarse and porous, while stoneware strikes a balance between durability and aesthetic appeal but still lacks the fine finish that porcelain can achieve. Plasticine, on the other hand, is a non-drying modeling clay that is not used for firing;
