What are the three main clay families used in ceramics?

• A. Earthenware, Stoneware, Porcelain
• B. Clay, Cement, Glass
• C. Ceramics, Glass, Metal
• D. Plastic, Porcelain, Stone

Answer: (A)

Clay bodies in ceramics are grouped by firing temperature and how much they vitrify. The three main families are earthenware, stoneware, and porcelain. Earthenware is fired at lower temperatures and remains porous unless glazed, often reddish or buff in color and easiest to work with. Stoneware is fired hotter, becomes vitrified and non-porous, producing a tougher, more durable ware. Porcelain is fired at the highest temperatures, with a fine grain that yields a white, often translucent product when thin, and it is very strong. These categories capture the standard range of clay bodies used by ceramists and explain why each is suited to different kinds of ceramic work. The other options mix in non-clay materials or misclassify what counts as a clay family.
