Purple clay pottery

Purple clay pottery

　　Yixing purple clay pottery originated in the Song Dynasty. By the Yuan Dynasty, the firing techniques of purple clay pottery had gradually matured, and inscriptions and carvings began to appear on the vessels. In the mid-Ming Dynasty, Yixing purple clay teaware became extremely popular and was hailed as the finest among all types of teaware. During the Qing Dynasty, the craftsmanship of Yixing purple clay pottery became even more refined, introducing a new style that incorporated seal carving, calligraphy, and painting as decorative elements. In the early 20th century, the production of Yixing purple clay pottery flourished, with over 10 dragon kilns operating year-round. In 1932, the annual output reached more than 2.2 million pieces. The product range included over a thousand varieties such as teapots, teacups, vases, flowerpots, clay pots, and figurine sculptures, characterized by generous shapes and classic, elegant colors. Teapots made from purple clay preserve the flavor of tea without altering it, maintain the color of stored tea, resist spoilage even in hot weather, remain comfortable to hold without getting too hot, and develop a richer, glossier sheen the longer they are used.

Yixing purple clay pottery is made from a unique type of natural, multicolored clay—purple clay—distinct from red clay. Its basic colors include vermilion, purple, and beige. The clay contains minerals and various oxides such as quartz, kaolinite, mica, and hematite. When fired at high temperatures around 1200°C, the color of the clay changes with the temperature, producing hues such as yellow like pear skin, brown like ink chrysanthemum, green like pine and cypress, red like maple leaves, purple like grapes, as well as white sand, crabapple red, and cinnabar purple.

The representative work of purple clay pottery, the "Purple Clay Hundred Longevity Vase," won a gold medal at the 1984 Leipzig International Fair.
