How to develop the glass manufacturing technology in China?

Glass was called Bo, Li and Shui Yu in ancient times. 1964, white beads were found in a tomb of the early Western Zhou Dynasty in Luoyang, Henan. 1975, thousands of glass tubes and beads were unearthed in a tomb of the Western Zhou Dynasty in Baoji, Shaanxi. After identification, this is a kind of lead-barium glass, which belongs to two different glass systems from the western soda-lime glass, indicating that China began to make glass as early as 3000 years ago in the Western Zhou Dynasty. From the Warring States Period to the Qin and Han Dynasties, the glass manufacturing industry further developed. The variety has increased, including monochrome glass such as blue, green, emerald and black, and multicolor glass beads commonly known as "dragonfly eyes". After the Three Kingdoms, the glass manufacturing method was once lost. During the Northern Wei Dynasty, Da Yue businessmen went to Datong to teach the technology of burning glass. At the beginning of Sui Dynasty, He Chou re-made green transparent glass with reference to porcelain-making technology. From the later generations to the Qing Dynasty, the glass manufacturing technology made continuous progress.
