Earthenware versus stoneware

Short answer

Earthenware is made from ordinary clay, fired at 1000–1100°C, porous, and requires glazing for watertightness. Stoneware uses refined plastic clay with flint and feldspar, fired at 1200–1300°C, is vitrified, non-porous, stronger, and often unglazed.

Differentiate between earthenware and stoneware.
