It is a lie to say that brass jewelry is processed on site. I watched the copper water enter the mold with my own eyes, but the mold was completely broken. I saw a ring, but I couldn't find the copper. Who can help explain one? Brass is worth a few dollars. Do I need to lie to you? Brass is priced by tons, and the retail price of one kilogram is tens of dollars. A brass jewelry is only a few grams, and the metal cost of a brass jewelry is only a few cents. Sitting on the side of the road to tell fortune is more profitable than making jewelry. Do you still need to do this kind of technical work to deceive people?

This kind of mold, called "lost wax casting", contains wax patterns. After the high-temperature metal liquid is poured into the mold, it replaces the position of wax and becomes a ring-shaped jewelry, but the material is still brass. Your question shows that you don't have any physical knowledge, just like you asked: you saw water put in the refrigerator and turned into ice. The water disappeared. The refrigerator must have lied to you. Ask a professional to explain! Water has changed from liquid to solid, but it is still water. Brass water changed from liquid cooling to solid, but it is still brass. How can you say that brass is gone? Is it a lack of life knowledge or a failure to graduate from primary school?
