My mother used to buy platinum jewelry "** Don't Say La".
So far there has been no problem at all. I wear it a lot.
-
Yes. All metals.
Even precious metals can change color.
But I'll come back after washing.
Experience!

Probably not, it depends on personal maintenance.

**There are two reasons why it turns white:
1.**Ring and platinum ring rub against each other, so that **jewelry surface is partially rubbed platinum white.
2.**Jewelry contains gold, when gold meets mercury, it will react with each other to form "gold-mercury", that is, it becomes "gold mercury contains gold", and the color is white.

**Mercury turns white. According to the understanding of the nature of the amalgamation, the main reason for the whitening is that it encounters mercury, a chemical reaction of amalgamation occurs, and a new chemical substance gold amalgam is produced, and the color of gold amalgam is just yellowish white, which is adsorbed on the surface of the jewelry, resulting in the phenomenon of whitening.
If there are ** and white gold rings on adjacent fingers, then the fingers are often active, which will cause ** and white gold to rub against each other, then the surface of the **ring may rub against white gold and look like **white.
Applications of mercury
The most common applications for mercury are in the manufacture of industrial chemicals and in electronic or electrical products. Mercury is also used in thermometers, especially in thermometers that measure high temperatures. Increasingly, gaseous mercury is still used in the manufacture of fluorescent lamps, while many other applications have been phased out due to health and safety concerns and replaced by the less toxic but much more expensive Galinstan alloy.
In addition, mercury is often used in gold mines because it can decompose gold from its minerals. It is used to make instruments such as barometers and diffusion pumps. Gaseous mercury is used in mercury vapor lamps. It is used in the manufacture of liquid mirror telescopes. Rotation is used to create a parabola of liquid.
shape, a telescope that serves as a primary mirror for astronomical observations, ** is one-third of that of an ordinary telescope.

What's the deal with platinum?
It may turn white, which may be caused by friction with white hard metal, or it may be caused by inadvertently contaminating the surface with mercury metal substances or daily necessities containing mercury metal. If the surface is white, it is recommended to send the surface to the gold store for a flame gun treatment to restore the surface of the project. The reason for the white color may also be the accidental contamination of the surface with mercury metal substances, or the accidental contamination of daily necessities containing mercury metal, resulting in white spots on the surface.
If the surface turns white, it is recommended to send the gold shop for processing, and let the gold shop master spray gold with a musket. The melting point of mercury is very low, and it will volatilize immediately when heated, so that the ** will return to its original appearance.
It's a brain-opening question, and of course, there is some truth to worry. After all, orange carrots contain a lot of pigments, and many people will worry about whether these pigments will be absorbed by the human body and enriched in the body's ** cells, so that their skin tone will turn yellow. >>>More
