What is the difference between red clay and white clay?

Aug 14

Red clay, often earthenware, contains more iron, giving it a warm reddish-brown color. It’s traditionally used for decorative pieces and rustic pottery. White clay, such as porcelain or white stoneware, has fewer impurities and produces a lighter, more refined look. Red clay usually fires at lower temperatures, while white clay can withstand higher temperatures. White clay is preferred for bright, clear glaze colors, whereas red clay can influence glaze tones. Both have unique textures—red clay is often more porous, and white clay is smoother. The choice between them often comes down to the desired aesthetic and function. Some potters love the earthy look of red clay, while others prefer the elegance of white. Each type responds differently to decoration and glaze. Studios may let students choose their preferred clay for projects.
