Some small gold shop owners are tampering with molds, and customers don't know. Some processors put the incoming materials into the mold and burned them, and then secretly left some gold at the mold mouth of the gypsum mold when taking the materials, but this place is very hidden. The processor will throw the plaster mold into the trash can in front of the customer, and then pick it up and take out the gold after the customer leaves.

Matters needing attention in gold processing:
1, gold on the scale:
At present, most of the gold weighing tools in gold jewelry processing shops are pallet Tian Ping. Some illegal gold jewelry processing shops tampered with this tray in Tian Ping, deliberately making it light and heavy. When someone processes gold jewelry with gold, they will put the gold in a light tray, and then put the jewelry in a heavy tray after processing, so that even if some gold is deducted from customers, it will not be discovered.
2. Stealing gold for silver:
Some illegal gold jewelry processing shops cheat when smelting gold and processing gold jewelry for customers. In the process of smelting gold for customers, some impurities, such as silver powder and copper powder, are mixed into the impurity removal powder and integrated with gold. What customers see on the surface is that the gold jewelry processing shop removes impurities from gold for them.
In essence, it is adulterated in molten gold in the name of removing impurities. The main purpose is to make it difficult for customers to find the weight loss after deducting the customer's gold.
3. touch gold in troubled waters:
Some gold jewelry processing shops deliberately leave a small amount of gold in gypsum molds when processing gold jewelry, and throw away the waste gypsum molds in front of customers, resulting in the illusion that there is no gold in gypsum molds; After customers leave, they will take back the discarded waste molds and take out the gold.
There are also a small number of illegal gold jewelry processing shops that cut off some "scraps" from customers' jewelry and secretly take them for themselves when customers are not paying attention. In order to make up for the original weight of customers' gold, fake "goods" were mixed in the smelting process.
4, "second" gold charge is good:
General gold jewelry processing shops will sell finished gold jewelry, and these gold jewelry are mostly processed for themselves. Fake "goods" are deliberately mixed into gold when processing, but they are sold as high-quality gold jewelry when selling. Most of these gold jewelry are boiled with sulfuric acid and generally look bright. People who don't understand "goods" are easily deceived by the appearance of these gold ornaments.
