Preserving jade
Pay attention to prevent bumps
Liu Jinshan said that because the hardness of jade is very high, generally do not worry that jade will be hurt. It is important to prevent bumps, especially from hard accessories, or from high places. "Because jadeite is formed in high pressure and low temperature, and the movement between the crust and the plate forms jade. These long journeys have made jade, so the life of the jade that has been handed down is very tenacious."
How to distinguish jade ABC goods
Liu Jinshan said: "There are many falsifications in the market. Many people like to blow the original BC goods into A goods. But B goods are so good jade, soak them with strong acid and alkali, and get out impurities. Then there are pits inside. In order to make up these pits, people will use resin glue to inject jade. From the surface, the jade is very bright and the color is good. However, its structure is destroyed, it is loose, and the compressive strength and toughness are greatly weakened, which affects its life. And durability. It looks very beautiful jade, it will age in about ten years, and slowly the color will be dark, it is not good to see. C goods are not entirely jade, use other jade to fill the color. This jade buy Come back, it will be devalued."
How to distinguish ABC goods? Liu Jinshan suggested that collectors can look at the gloss first. "A goods are shiny and shiny, with the luster of glass. Its surface is very smooth, there are no pits, no trachoma, and there is a convex feeling under the magnifying glass. The surface is reflective, fluid, and very aura. The gloss is waxy, and the surface can be seen uneven under reflected light. If you look inside, you can see the fuzzy spots between the particles. The gloss of C is the resin luster, the gloss is similar to that of B, and it looks dull. There are many mesh-like grooves downstream of the reflected light, the internal structure is ambiguous, or a cloud is blurred."
Liu Jinshan believes that it can also be judged by voice. "The sound of A cargo is very pleasant, and the tail sound is melodious and crisp. This is because the result of jadeite is not destroyed, and the overall goodness is good. B goods soaked with strong acid and alkali, due to the destruction of the structure, the sound is dull The tail sound is short, not as crisp as the A cargo. The sound of the C cargo tap is more dull, rough and short than the B cargo. The tail sound is short, not flexible, and soon disappears.
