The term 'porcelain piece' can refer to two different items. An EWER is a type of pitcher or jug, usually made of porcelain, with a wide base and a narrow neck. It is often used for pouring liquids such as water or wine. A teacup is a small cup, usually made of porcelain, used for drinking tea. It typically has a handle and a saucer to catch any spilled liquid. Both ewers and teacups are popular items in many households and are often used for decorative purposes.
