What is the difference between glass-bottom and glass-type jade?

To see whether a piece of jade is valuable, the first thing to look at is the quality of the jade, which will directly determine the "value" of the jade. The texture of your face is like the foundation of a girl's face. If the foundation is not good, no matter how good the cosmetics are, it will be difficult to save it. The same goes for the quality of jadeite. A clean base is very important. If there are some floating flowers or other decorations, it will be icing on the cake.

Jade quality is generally divided into glutinous type, glutinous type, ice type, high ice and glass bottom, and glass type, and the best grade among them is the glass type. You might say, aren’t glass bottom and glass type the same? Many laymen may think that they are both glass, but in fact there are differences between them.

As for the types, friends who are more familiar with it also know that it is related to the internal structure of jadeite. It is a division of the tightness of the arrangement of molecules inside jadeite. It is a microscopic grade classification. As for the bottom, it can be said to be an overall macroscopic representation of jadeite.

The bottom is an external comprehensive performance that includes texture, water, transparency, and even fluorescence (glue feeling). Only when these requirements are met can it be called glass type. As for the glass bottom, it is only close to glass grade, but has not yet reached the glass grade. In a word, glass-type jade is much better than glass-bottom jade. Therefore, we often hear that "a good bottom does not necessarily mean a good type". This means that if the internal structure of jade is well arranged, it does not mean that there are no impurities or that the color will necessarily be good.

Taking our cotton fabric as an example, a fabric with a cotton content of 50% can also be considered cotton, but it is definitely not on the same level as 100% pure cotton. So there is a difference between glass type and glass bottom. Don't confuse them. The nine sons of the dragon are all different. Although they all belong to glass, there are still differences.

Sometimes we may see many merchants saying that this is glass jade, and you will think, is glass jade so cheap? Is jade no longer valuable? Did you miss out? Of course not. There is no such thing as a free lunch. Even if it does, it won’t hit you. Besides, you have to believe that “you get what you pay for”. There is no such thing as “good quality and low price” for jade.

There are relatively many glass bottoms, but there are indeed very few with glass types, so the prices are naturally different. The glass bottom is only close to the glass type, but its value is not as high as the glass type, so you still need to be careful to distinguish them. However, they all belong to the category of glass, it’s just pure or impure. As long as you have a standard in your heart, that’s enough!
