Yellow wax stone has always been a major item in the collection of Kistler. The earliest excavation and prestigious number were Chaozhou Yellow Wax Stone. Taishan Yellow Wax Stone became famous, and Yunnan Yellow Wax Stone was famous this year. The latter two are "big late", Taishan Yellow Wax Stone Even "renamed" for "Taishan jade", and Yunnan yellow wax stone was added the "Yellow Dragon Jade" reputation. There are two ways to collect yellow wax stone, one is natural ornamental stone and the other is stone carving.
Collectors believe that as long as the weight and color of the cockroaches are mastered, the true and false yellow wax stone can be judged by the naked eye. Collector Mr. Cao said that there are natural transitions between different colors on the real yellow wax stone, and fake yellow wax stone is difficult to do; secondly, the resin fake yellow wax stone is much lighter. "In fact, this kind of fraud is the easiest to expose." One collector said that the most convenient and quick way is to use fire.
Other falsification methods are emerging one after another. For example, natural ornamental stones have not been modified by any carvings, but some merchants have moved their hands and feet in order to achieve better shape effects.
According to Mr. Cao, a collector of Chaozhou, “hands-on†is mainly used to modify the surface with a jade polishing machine.
Be wary: soak with oxalic acid to make the color bright
Whether it is natural ornamental stone or stone carving, the most common falsification method is to soak it in oxalic acid to make the surface color more vivid. There is also a coloring and falsification technique like Emerald. “ Soaking with oxalic acid is extremely destructive to yellow wax stone.†An expert told reporters that this stone will be very beautiful in a short time, but soon the texture will be loose due to the destruction of the surface layer, and the surface will feel dry. "For a stone with a tight texture, the oil can be maintained for one year, and the stone damaged by oxalic acid needs to be smeared to maintain its oiliness."
Put Heyuan Stone as Chaozhou Stone
Another falsification technique is to cover up the cracks in the stone. "For example, the price of a good yellow wax stone market is 10,000 yuan, and the crack may be worth only 5,000 yuan, but this crack is difficult to see from the surface, the buyer may even buy it with 12,000 yuan, eat A big loss, a collector who has suffered from such a loss told reporters that he learned that after losing, in order to avoid this loss, the collector can check the stone as long as it is transparent through the flashlight.
In addition, some merchants have glued the broken yellow wax stone together with glue, which is not easy to see.
Another kind of falsification technique is not so simple and intuitive, and it requires a wealth of experience to distinguish. Collector Mr. Cao told reporters that many beginners have eaten this loss: "There are many producing areas of yellow wax stone, the value of different stones in the place of production is different, and there are merchants who are cheaper and expensive." For example, the Chaozhou yellow wax with big fists The price of stone is at least 10,000 yuan. In recent years, Heyuan, which is not far from Chaozhou, has also discovered the yellow wax stone with almost the same texture. However, the market price of the size of the fist-shaped yellow wax stone is only 2,000-3,000 yuan. Many merchants will treat Heyuan Stone. Chaozhou stone is for sale. Mr. Cao suggested: "It is best to resort to the experienced 'old hands' to help judge the newcomers."
