Sansai glazing
Sansai glazing is a ceramic glazing technique characterized by the use of three contrasting glaze colors applied to the surface of pottery. The term sansai (Japanese: 三彩) literally means "three colors".
In this technique, different colored glazes are applied to a ceramic vessel in separate areas or allowed to flow together during firing. Traditional sansai color combinations often include green, amber, and cream tones produced by copper, iron, and other metal oxides in the glaze.
The technique originated in China during the Tang dynasty, where it became known as Tang sancai. The style later influenced ceramic traditions in other parts of East Asia.
In Japan, sansai glazing appears in certain historical ceramics and in decorative wares where multiple glaze colors are used to create vivid visual contrast. The glazes may be applied to sculptural forms, vessels, or architectural ceramics.
During firing, the glazes can interact and flow together, producing irregular transitions between colors and creating dynamic surface effects.
