Sancai
Sancai is a versatile type of decoration on Chinese pottery mainly using the three colors of brown, green, and a creamy off-white for decoration. It is particularly associated with the Tang Dynasty. Therefore, it is commonly referred to as Tang Sancai in Chinese.
It uses lead-glazed earthenware, and was much easier and therefore cheaper to make than Chinese porcelain, and suitable for making large figures, if necessary made up of several molded sections assembled after a first firing. Flatware dishes and other vessels were made in the technique as well as figures.
