lead glaze

Toxic pottery finish

Lead glaze is a ceramic coating containing lead oxide, which lowers the melting point and produces a smooth, glossy finish.

Traditional pottery often used lead glazes for their rich colors and shine: The antique earthenware had a distinctive lead glaze.

Health concerns over lead leaching into food and drink have largely eliminated their use on functional tableware, though they remain in decorative ceramics and historical restoration.
