Generally, the cinnabar content of natural cinnabar bracelets is basically about 80%, but there are many cheap cinnabar on the market, and their content is mostly below 50%, and some are even less than 30% Such cinnabar looks bright when it is first bought, but after a period of play, it finally becomes a small briquette.
The main ingredient of cinnabar is mercury sulfide, which is a harmful substance to the human body and cannot be taken internally. Because cinnabar bracelets contain such toxic substances, it is recommended not to wear them close to the body. Of course, before cinnabar did not become gaseous mercury, it was actually harmless to the human body, and the mercury sulfide contained in it was non-volatile, basically insoluble in water, and had very low toxicity. When wearing it in contact with **, as long as there is no allergy, there is no problem. So it depends on how well you take care of the lost sand bracelet.
The main component of cinnabar is vulcanization, which is basically non-toxic, but once the sulfidation is heated, it will decompose into a sum of sulfur, which can further generate unsteam, and sulfur can generate sulfur dioxide. In other words, this kind of substance will become harmful once heated, so when wearing it, if it is valuable in a high temperature environment, it is best to take it off.
Secondly, cinnabar bracelets are afraid of washing, cinnabar bracelets can not be wet when wearing, many cinnabar bracelets that look pure in color are mostly in the post-production process, artificially extracted the iron components in them, and the cinnabar bracelets stained with water will not only decolorize, but also become soft and even disintegrate. Cinnabar bracelets should not be soaked in water for a long time, so avoid getting wet when wearing cinnabar bracelets, take them off when washing clothes and bathing, and put them in a soft jewelry box for preservation. If you accidentally let the cinnabar bracelet get wet, wipe it with a soft cotton cloth in time.
Cinnabar bracelets not only can not be touched with water, but also can not touch fire and high temperature, because cinnabar contains a small amount of realgar, realgar will emit harmful substances such as mercury sulfide when exposed to fire and high temperature.
