Sansai (Three-Color Glaze Ware) / 三彩
Sansai refers to a type of low-fired earthenware decorated with multiple lead-based glazes. The technique was perfected during the Tang dynasty. The most vibrant examples, known as Tang Sansai (Tang three-color ware), were produced primarily from the late 7th century to the first half of the 8th century in China.
Although the name "sansai" means "three colors," typical Tang sansai pieces feature combinations of white, green, and amber (brown), though some examples include a fourth color, such as cobalt blue, or use only two colors. The sansai technique was later inherited and developed into Liao sansai and Song sansai during the Liao and Song dynasties, respectively.
