The jade inlaid with opaque glass and made in ancient China was very popular. Its production began with the influence of Western jade. Glass jade made in the Warring States Period contained more lead and barium. Later, glass was made by using unique techniques. The unique design of patterns of ancient incantation, concentric circles, and seven stars in Warring States Jade is based on the Western Asian jade and formed its own style in the Warring States Period. In addition to accessories, some are also embedded in mirrors and utensils.
