What is Colored Glaze (Colored Glass)?
Colored glaze or Lazurite, called “Liu-li” in Chinese, is a type of multi-hued crystal glass which dates back to China’s Tang Dynasty (618BC-907BC), more than one thousand years ago.
During the Tang Dynasty, ancient Chinaprospered and its architecture flourished. A form of glazed pottery known as “Tang tri-colored glazed pottery” had already earned great fame in the region. A potter succeeded in experimenting with pottery by adding a material used in the production of tile and this produced the signature translucency associated with the world-famous Colored Glaze (Liu-li) today. The term “Liu-li” was first found in the Buddhist Sutra. In religious scripture, the “Light of Liu-li” signifies the elimination of greed and desire, illumination of the spirit of Buddhism and spreading the glory of Buddha far and wide.
The material used in Colored Glaze is actually adopted from the raw material used to produce precious crystal glass in the West. Crystal glass is made from a combination of glass and lead oxide. While the proportion for mixing glass and lead oxide varies from country to country, generally speaking, when the percentage of lead oxide reaches 24% and above, the translucency and refractive quality of the glass reaches an excellent level.At the same time, the crystal glass is also heavier, softer and in prime condition for crafting into fine works of art. Colored Glaze (Liu-li) is comparable to European and American crystal glass products well-known for their high quality and is thus superior in price and quality to ordinary glass products.
