brass jewelry pros and cons
Jewelry made of brass. Brass is cheap, so it is often used to make jewelry. At the same time, technicians engaged in jewelry also use brass to make relatively large-scale conceptual jewelry.

Advantages and disadvantages of brass jewelry
1. Advantages:
It is cheaper and easy to process. Many people use brass to make large-scale conceptual jewelry, especially the casting process. Because a large amount of metal is required for casting. And after some anti-oxidation treatment, the gloss remains pretty good. The most commonly used brass in making jewelry is to make mending. The so-called mending is, for example, a certain amount of brass and sterling silver melted when 925 silver is added.
2. Disadvantages:
Many people are allergic to it. So most studs or earrings are made of pure silver instead of brass.
Jewelry production materials: generally divided into three categories: metal materials, non-metal materials and various synthetic materials.
1. Metal materials: In the production of jewelry, the most commonly used precious metal materials are gold, silver and platinum and their alloys. The commonly used gold alloys are mainly 18K gold, 14K gold, 12K gold and 9K gold; the commonly used silver is 925 silver ; The commonly used platinum is platinum 900 (marked as Pt900), platinum 950 (marked as Pt950), and now platinum 990 (marked as Pt990) is also beginning to appear in the market.
2. Non-metallic materials: Non-precious metal materials related to jewelry production mainly refer to simple substances or alloys such as copper, zinc, aluminum, lead, and nickel. Copper and zinc are the most commonly used. The copper used in jewelry production is mainly pure copper and copper alloys.
(1) Pure copper (electrolytic copper, oxygen-free copper): specific gravity 8.96, melting point 1083°C, hardness slightly higher than gold and silver, easy to oxidize and sulfide. Good ductility and plasticity, suitable as a base material for jewelry.
(2) Copper alloy: The common copper material for jewelry is copper alloy. Commonly used ones are: copper (15% zinc), brass (15-45% zinc), bronze (5-20% tin).
(3) Copper-based alloys: In recent years, some copper-based alloys have appeared in China's Jiangsu and Zhejiang areas, as well as in Shanghai, China. Some of their color and corrosion resistance are close to K gold materials, and they are promising imitation gold jewelry materials. It is rare gold or sub-gold, and the color mark is KF.
3. Various artificial synthetic materials: such as synthetic glass, gum, plastic, etc.
Cleaning of brass jewelry
Copper is difficult to clean after oxidation. Generally rub with toner, then wash with water. After cleaning, waxing is required. If the oxidation of brass jewelry is serious, the toner may not be able to clean, then you need to use potassium permanganate. Procedure and front same. After wiping, be sure to wax after cleaning, otherwise it will oxidize again. It is best to use paraffin wax when waxing. Apply a layer evenly on the surface of the article. Waxing is similar to polishing. There are two requirements: one is uniform, and the other is to be thin to ensure that the surface of the article is no longer in contact with the outside air, and at the same time feel Less than a thick layer of grease is enough.
