The so-called Guyuexuan refers to a kind of arts and crafts in the Qing Dynasty (A.D.1644 ~1911). Gu Yue Xuan began in the Kangxi period of Qing Dynasty (A.D. 1662 ~ 1723). It is made by coating the glass tire with enamel and firing at high temperature. In the past, because of its extremely difficult technology, very small utensils, such as snuff bottles and cigarette trays, were only made in royal kilns.
