Ceramic tableware is made from clay or sand that’s been fired or baked.
Earthenware is a porous terra-cotta material fired at lower temps. It is the most affordable and least durable.
Porcelain are clay-and-mineral pieces, extremely thin (almost translucent), but also chip-resistant. It is the most expensive.
Stoneware is handmade from dense clay, resulting in unique textures.
