Earthenware, stoneware, and porcelain are all types of ceramics that differ in terms of their composition, firing temperature, and properties. Earthenware is made from clay that is fired at a relatively low temperature and is porous and opaque. Stoneware is made from a denser clay that is fired at a higher temperature and is more durable and non-porous. Porcelain is made from a type of clay that is fired at an even higher temperature and is translucent, strong, and non-porous.
