At present, most of the golden weighing tools in jewelry processing stores are tray balances. Some illegal gold handy processing processes are ghosts on this tray balance. Light, a tray is heavy. When they meet someone to process the jewelry with gold, they put the gold in the light pallet. After processing, the jewelry will be placed in the heavy tray. I don't know the ghost. Two of fraud: "Wang Shui" stripping gold "Wang Shui" is a chemical liquid with concentrated nitric acid and concentrated hydrochloric acid. Chemical reactions occur, but "Wang Shui" can easily dissolve gold, so some illegal jewelry processors can use this simple chemical reaction to clean the gold jewelry for customers, so that customers can not see it with the naked eye. , Was peeled off the gold. Those who claim to clean the gold jewelry for customers are often hidden in this kind of "cat greasy".

In essence, they, they, they, in essence, they, in essence, they, in essence, they, in essence, they, in essence, they, in essence, they, in essence, they, in essence, they, in essence, they are essentially. In essence, they are essentially. It is based on the name of miscellaneous objects and adulteration in the melting gold. The purpose is to make it difficult for customers to notice the amount of portion after deducting customer gold. The fourth fraud: When the muddy water is touched, some of the plaster molds are left in their plaster molds, leaving a small part of gold left, and throwing away the waste plaster mold in front of the customer, resulting in a gypsum mold. The illusion of gold, after the customer left, they took the discarded waste model and took out the gold. There are also a small part of the illegal jewelry processors who cut off some of the "corner materials" on the customer's hand decoration when the customer is not paying attention. "".n1 morenBleak
