Origin of frog skin glass beads

Why are old glass beads made of frog skin precious? There are two reasons for this:

First, because of the particularity of old glass materials, its technology is extremely complicated and difficult, and the production technology of old glass is quite complicated. From fire to water, there are dozens of processes, and they are mainly made by hand.

The difficulty of mastering the temperature depends partly on skill and partly on luck. The output is low. More crucially, old glass is not like gold and silver, and can be recycled. Once there is a little problem, many people's efforts will be in vain.

Secondly, old glass is not only a material, but also an ancient cultural heritage. More importantly, glass products are unique, and no two glass products are exactly the same. This is a feature that modern glass or crystal products can never replace.

China has a long history of making glass, and there are primitive glass beads among the Western Zhou cultural relics unearthed. By the Warring States Period to the Han Dynasty, the craftsmen's control of the furnace temperature had been stable, and the quality of the glass was also guaranteed. In the plastic arts, adhering to the social atmosphere at that time, the glass production in this period was rigorous, dignified and generous, both technically and artistically, which was the first peak in china glass.

In ancient times, colored glaze had many aliases, such as: moving flowers, moving flowers, medicinal jade, mirabilite, fan glass and so on. The last "Fan Glass" means from foreign countries, but in fact, glass has been recorded in China for a long time. There were glass earrings in the Western Zhou Dynasty more than 2,000 years ago, but they were not handed down ... The glass moved westward and spread to Central Asia and West Asia. In the Qing Dynasty, a large number of glass products flooded into China by sea and land. Many people thought it was imported, and it was called "model goods", which was actually a recognition of our ancestors.
