The identification of glass tea ware requires careful observation. Firstly, it is important to look at the transparency and brightness of the glassware surface. High quality glass should be extremely transparent and have a slightly shiny surface. Secondly, tap the edge of the glassware with your finger; if it produces a crisp clear sound, it is made from high quality materials. Thirdly, look at the edges of the glassware; they should be smooth and flat without any defects such as scratches or chips. Lastly, check whether there are any signs that indicate its authenticity on the bottom of the product; it could be a logo or serial number.
Glass, anciently known as “Liu Li” or “Liu Li”, is a colored semi-transparent mineral. Tea sets made of this material give people a bright and shining feeling. Although the Chinese Liu Li production technology started early, it was not until the Tang Dynasty, with the increasing exchanges between Chinese and foreign cultures and the continuous influx of Western Liu Li wares, that China began to burn Liu Li tea sets. The plain yellow Liu Li tea cup and plain yellow Liu Li tea tray offered by Emperor Xi Zong of Tang Dynasty in Fengmen Temple’s underground palace in Fufeng are authentic Chinese Liu Li tea sets. Although the shape is original, the decoration is simple, the texture is mixed, and the transparency is low, it shows that Chinese Liu Li tea sets had already started in Tang Dynasty and were considered precious at that time. In Tang Dynasty Yuan Zhen once wrote a poem praising Liu Li saying that “it is colorful like ice, nothing can block its dust; diners cannot be seen from it, which should be given to jade people”.

No wonder in the Tang Dynasty, when offering items to the pagoda and bone relics of the Famen Temple, porcelain tea sets were also included. In the Song Dynasty, unique high-lead glass utensils appeared one after another in China. During the Yuan and Ming Dynasties, large-scale glass workshops appeared in Shandong and Xinjiang. During the Kangxi period of the Qing Dynasty, a royal glass factory was also set up in Beijing. However, from the Song Dynasty to the Qing Dynasty, although there were production of glass parts and they were expensive, they mainly produced glass art products, and only a small number of tea sets products were made, and never reached a scale production for glass tea sets.

In modern times, glassware has developed significantly. Glass materials are transparent, shiny, and highly malleable in shape and various in use. When brewing tea with a glass cup, the vivid color of the tea soup and the tenderness of the tea leaves can be seen clearly throughout the process of brewing; moreover, the gradual unfolding of the leaves can be considered as a dynamic art appreciation. Especially when brewing different kinds of famous teas, glassware is crystal clear with misty fog inside; clear green liquid can be seen with buds standing upright. It is pleasing to watch and unique in style. Furthermore, glassware is inexpensive yet beautiful – making it a popular choice among consumers. The downside to using glass products is that they easily break and can be hot to touch compared to porcelain ware.
