1. Two stages of jadeite bleaching and glue injection. The first stage is bleaching, also known as yellowing, that is, the original jadeite stone that has been cut into pieces or the jadeite that has been polished is removed by chemical treatment (which may be caused by filling cracks with iron compounds). The second stage is to inject human polymers and even add green pigments.

2. Generally, the transparent resin is injected by the method of vacuum negative pressure. The refractive index of this resin is close to that of jade. After polishing, it is almost no different from high-grade jade. If colorant is added during filling, it is called B+C jadeite. Therefore, the objects of bleaching and filling treatment are generally middle and low-grade jewelry and blanks.

3. Then the injected glue is mainly wax or resin to fill the pores and cracks, which makes the jadeite more firm. Some dyes and polymers are injected together to make the treated jadeite both firm and colorful. The original jadeite stone is injected with glue. Glue injection is one of the most commonly used processes for processing jadeite B and C goods.

4. irradiate jadeite with purple light. If there is a strong fluorescence reaction, it is injected with jade. Boil jadeite in cold water until it boils, and the texture becomes turbid and even the color becomes pale. Observing the surface structure with a magnifying glass, the structure is irregular, and there are more jadeite injected in the fracture.

5. How to interpret the answer will be more accurate. It can be said that glue injection is not uncommon in jewelry and jade circle, and it is also one of the most commonly used jade B and C processing technologies. Because of the loose structure, the jadeite that is strongly pickled will be filled with glue and then processed.

6. Jade glue injection is an optimized fake jade. Glue-injected jadeite is made by cleaning jadeite with strong acid, and then injecting glue to fill the cracks. Glued jadeite can see green lines under strong light, and some can't see the lines clearly but are turbid, and the luster is still very poor.
