What is the difference between glaze and crystal (Western crystal glass).
A. There is a clear distinction in the history books.
There is a similar record in the Diamond Sutra. Among all the Buddhist scriptures in China, the first five categories of Buddhism are known as gold, silver, glaze, enamel* a mollusk* agate, the latter two are said to be crystal, and amber, glass There are many things, which means that glaze is a recognized treasure of Buddhism; glaze is very different from crystal and glass.
B, different chemical composition
The main components of natural crystal, glass and glass are all silicon dioxide.
Contemporary national-level authoritative monograph "Chinese ancient glass research" records: the ancient Egyptian "Féon" (that is, the ancestor of Western crystal glass) the proportion of silica 92% (not transparent) -99%, China's Zhou Dynasty glass The ratio of silica is only slightly more than 90% (transparent). The difference of 9% is the biggest difference between glass and crystal.
C, detailed explanation of ingredients
The ancient glaze was made by adding glazed stone to the glaze. The glazed stone is a colored crystal material. The main component should be silica. The glaze is a natural and artificial refining. After the ancient formula, you can change the structure and physical properties of the crystal, and there are obvious differences in shape, color and transparency.
The medicine jade of the Ming Dynasty should have some differences in the formula of the glaze, so the color of the jade in the Ming Dynasty changed little and was not transparent.
The grade of glaze actually depends on the raw materials and preparation method of the glaze. This is the secret of non-transmission since ancient times. It is because of the existence of the glazed mother that the ancient Chinese glass and crystal and even the western crystal glass "Faance" "There is a 9% difference in composition.
The so-called glass lucky, safe, and have a great relationship with the glass.
