To distinguish between stoneware and earthenware, examine the clay's color and texture. Stoneware is typically denser, has a smooth surface, and is often gray or brown, while earthenware is more porous, softer, and usually reddish or terracotta in color. Additionally, you can check for a glazed finish; stoneware is usually fully vitrified and less likely to absorb water, whereas earthenware may be more absorbent. A simple water test—placing a few drops of water on the surface—can help; water will bead on stoneware but may soak into earthenware.

Stoneware can be fired at higher temperatures than earthenware due to its unique composition, which typically includes a higher percentage of kaolin and other strong clays. This allows stoneware to vitrify more thoroughly, resulting in a denser and more durable product. The higher firing temperatures also facilitate the development of a glassy phase that enhances strength and resistance to moisture absorption, making stoneware more robust than earthenware. Consequently, stoneware is better suited for functional items like cookware and dinnerware.
