What is the metal used for jewelry? What kind of brass can be used as jewelry?

Precious metal materials such as gold, silver and platinum are used for jewelry, non-precious metal materials such as copper and zinc are used, and metal alloy materials are used for jewelry welding.

Precious metal materials refer to eight elements: gold (Au), silver (Ag), platinum (Pt), palladium (Pd), iridium (Ir), ruthenium (Ru) and rhodium (Rh).

Brass is an alloy of copper and zinc. If brass consists only of copper and zinc, it is called ordinary brass. If it is a variety of alloys composed of more than two elements, it is called special brass. For example, a copper alloy composed of lead, tin, manganese, nickel, iron and silicon. Brass has strong wear resistance. Special brass is also called special brass.

Brass is cheap, so many people use brass as brass jewelry.

Cleaning method of jewelry:

In order to protect the luster of gold jewelry, a thin layer of nail polish can be coated on it.

If there is a black silver film on the surface, 2 grams of salt, 7 grams of baking soda, 8 grams of bleaching powder and 60 ml of clear water can be used to make a "gold cleaner". Put the gold jewelry in a bowl, pour the detergent, take it out after 2 hours, rinse it with clear water (preferably not hard water), bury it in sawdust to dry, and then wipe it with a soft cloth.

Ring inlaid with gems Roll a piece of cotton with a matchstick, soak it in a mixture of toilet water and glycerin, scrub the frame, and then polish the ring with flannel. Never scratch with sharp objects such as blades.

Salt and vinegar are mixed into a cleaning agent, which can be used to wipe pure gold jewelry and make it last forever.

Toothpaste wiping or scrubbing with hot rice soup can also restore the luster of gold jewelry.

Mixing soot with the same amount of vegetable oil, and putting gold jewelry in it for scrubbing will make gold jewelry shine.

Of course, it is recommended to send it to a bigger gold shop with specialized technicians, reagents, ultrasonic cleaning and other equipment for cleaning.
