Why does cinnabar turn white when burned with fire?

High temperatures change the structure of the material. Cinnabar, also known as cinnabar, dansha, red dan, mercury sand, is a natural ore of mercury sulfide (chemical name: HGS), bright red, with diamond luster to metallic luster, belonging to the trigonal crystal system.

Fire test: take a little cinnabar and burn it with fire, there will be a popping sound and gelatinous liquefaction, the color turns from yellow to brown, and finally turns black, and repeatedly blisters, there is white smoke after the bubble bursts, it will not be ashed after burning for a long time, and the honeycomb traces will be left after cooling. Cinnabar is mainly composed of mercury sulfide, but is often mixed with realgar, apatite, asphaltene, etc.

Whether cinnabar has a sedative-hypnotic effect is unclear. It has the effect of detoxification and antiseptic; Topical application inhibits or kills bacteria and parasites. Cinnabar is a mercury compound.

Mercury has a special affinity for hydrophobic groups in proteins. At high concentrations, it can inhibit a wide range of enzymes and activities. Mercury enters the human body, mainly in the liver and kidneys, causing liver and kidney damage, and can directly damage the central nervous system through the blood-brain barrier.

Cinnabar turns white when burned with fire, and this is because some of their pigments metamorphose at high temperatures, which is the reason why after some calcination, it turns white.

Cinnabar will precipitate mercury when exposed to fire, and mercury is toxic, which is more harmful to the human body.

Therefore, when using cinnabar ** disease, it is necessary to grasp the dosage, and at the same time, it is necessary to remember not to forge by fire.

High temperatures change the structure of the material. Cinnabar, also known as cinnabar, dansha, red dan, and mercury sand, is mercury sulfide.

I just burned it, one bought the finished powder, there is not much taste, the other burns it with tweezers will stick a little sticky, I don't know if it is more glue.

What does cinnabar look like when burned with fire I just burned it, one bought the finished powder, there is not much taste, and the other is a little sticky when pinched with tweezers after burning, I don't know if it is more glue.

Because it was sulfided.

Cinnabar is sweet and slightly cold, the texture is heavy, traditional Chinese medicine believes that cold can reduce fire, heavy can be suppressed, and cinnabar is the main heart meridian, so it can be calmed and calmed at the same time as the real fire of the heart meridian, which is an important medicinal material for clearing the heart and calming the nerves. Cinnabar is especially good at heart palpitations caused by hyperactivity and restlessness.

Symptoms such as sluggishness, irritability, irritability, insomnia, and dreams.

Cinnabar is slightly cold, good at clearing the heart, do not use it externally or internally, it has the effect of clearing heat and detoxifying, and can be used for hot poison sores and ulcer poisoning, sore throat.

Sores on the mouth and tongue. 1. Avoid iron and magnets.

Cinnabar is a natural ore that has the effect of calming the heart and calming the nerves, clearing heat and detoxifying, but it cannot be taken for a long time because of toxicity. And because of its special composition, it cannot be stored in iron or cleaned with salt water. Moreover, cinnabar has a strong yang magnetic field, and it is also taboo to use magnets.

and so on, destroying its own magnetic properties.

2. Cinnabar is toxic, not suitable for a large amount or a small amount of long-term use, because its mercury is easy to make human protein, and can accumulate in the body during childbirth, so pregnant women and kidney insufficiency.

is prohibited.

3. Cinnabar can undergo chemical reactions when heated for a long time.

Mercury and other toxic substances can be precipitated and increased toxicity, so cinnabar should also be used to prohibit calcination with fire.

I think it's mainly because after encountering fire, its temperature rises, which causes some of the substances in it to change.

It may be because after the cinnabar is caught in fire, some of the substances in it turn black after burning.

This is because cinnabar is a special material, and after being burned by fire, some chemical reactions will occur before turning black.

This is because the color of cinnabar itself turns black.

Summary. I once bought a red embroidered cotton shirt but accidentally put it in hot water and found that the shirt turned white. Solution:

1.Put the shirt in cold water, then add a teaspoon of alkaline laundry detergent, scrub it by hand, rinse it in warm water, rinse it in clean water, and finally dry it. 2.

Put the shirt in warm water, add a teaspoon of red wine, scrub it, then rinse it in clean water and let it dry. Extended content: When washing, you should pay attention to the temperature control to avoid damage to the clothes, and also pay attention to the choice of laundry detergent, try to choose a mild laundry detergent to avoid damage to the clothes.

I'm sorry I don't understand, but can you elaborate on that?

In response to your question of judging and litigation, I can provide the following solutions:1Soak the sand in warm water, then wash it with clean water and repeat several times until the sand turns white.

2.Put the sand in warm water, add a small amount of alkaline substances, such as caustic soda, washing powder, etc., soak for a period of time, and then wash with water until the sand turns white. In addition, the reason why the sand is white is because the hot water contains oxides, which will change the color of the surface of the sand, so in order to make the sand white, it is necessary to wash off the oxidation slippery.

The whitish surface of cinnabar does not necessarily mean that it is real. Cinnabar is a red mineral made from mercury-sulfur compounds that has historically been used in pigments and medicines. Since mercury is a toxic metal, cinnabar is no longer used to make cosmetics or medicines.

The judgment of authenticity needs to be comprehensively considered from many aspects.

First of all, the whitish cinnabar may be due to the effects of oxidation or sunlight, resulting in the appearance of a white substance on the surface. This change does not affect the composition and structure of cinnabar, nor does it mean that it is fake. However, if there are black spots on the surface of the cinnabar, it means that the mercury in it has been oxidized, and the cinnabar has been destroyed and can no longer be used for any purpose.

Secondly, real cinnabar should have the characteristics of hard and brittle and brittle, with a delicate granular structure in section, bright red without yellowing. Fake cinnabar may have added other substances, such as gypsum, loess, etc., so that the hardness is not enough, the color is uneven, and it will leave a gray residue after being melted by fire. Therefore, if you want to determine the authenticity of cinnabar, you can try tests such as melting, rubbing, or heating it.

In short, the whitish surface of cinnabar cannot be used as the only basis for judging the authenticity of its jujube, and it needs to be considered in many aspects. If you want to buy cinnabar or identify the authenticity of cinnabar, it is best to find a professional appraisal agency or a senior collector to appraise it, so as not to be deceived. <>

Good evening, the main ingredient of cinnabar is mercury sulfide.

When it is exposed to a high-temperature open flame environment for a long time, it undergoes a decomposition reaction to generate elemental sulfur and metallic mercury, which will become hot during the exothermic process, and at the same time, metallic mercury will be sublimated into mercury vapor that is highly toxic to the human body under high-heat conditions. If it is not mercury.

Processing practitioners, please do not burn cinnabar at will!
