Question 1: How to distinguish the authenticity of cinnabar? Cinnabar is a purified product of sulfide mineral cinnabar, and its commodity specifications are divided into Zhu Bao sand, mirror sand and douban sand, all of which are commonly used Chinese medicines. Its main component is mercury sulfide. It is toxic and should not be taken in large quantities for a long time to prevent mercury from accumulating in the human body and causing poisoning. Cinnabar is resistant to aluminum. After grinding with aluminum products, it gradually turns dark gray, giving off a pungent smell of rotten eggs. Leave it overnight and turn it into silver-gray powder (that is, mercury and aluminum poisoning). It has been reported in the past that the easily mixed products of cinnabar are realgar and red powder. Recently, a new counterfeit product was discovered, which looks very similar to Zhu Baosha. To prevent misuse, the comparison between them is as follows:

Authentic products are small particles of different sizes, with bright red or dark red powder attached to the surface, which can be wiped off with cotton balls, showing diamond luster, heavy and brittle. Squeeze small particles with nails to get bright red powder. Counterfeit products are small particles with uniform size, with dark red powder attached to the surface, dyed red by hand touch, and squeezed into silver-gray powder by nails.

Fire detection method 1: take a little genuine product, wrap it in tin foil and heat it, the color will turn brown first, then black, and make a crackling sound at the same time; Liquefied into colloid and foamed repeatedly; Burning for a long time will ash, and after cooling, it will leave honeycomb traces. After the counterfeit money is heated in the same way, there is no other change except that the color changes from dark red to black. Method 2: Put a little genuine product on white paper, heat it under the paper, change it from bright red to black, and leave the flame. The original color is restored, and the white paper is not stained. Fake goods change from dark red to black when heated, and cannot be recovered after leaving the flame, and the white paper is dyed light red. Method 3: Pick a little genuine powder with a matchstick and light it. You can see bright and tiny mercury beads on the burnt matchsticks. Counterfeit products have no such reaction. Method 4: add a small amount of iron powder into the test tube, seal and heat, and form mercury beads or mirrors on the wall of the test tube. After the fake is heated, the tube wall is reddish, and the small particles turn silver gray.

Try to take some real water, put it in a beaker filled with clear water, shake it well and leave it for a while. The water is not dyed and the sediment is dark red. After the counterfeit money is put into the water, the water is dyed light red, most of the sediments are silver gray, and a few are dark red.

Question 2: How to distinguish between true and false cinnabar jewelry It is very simple to distinguish between true and false cinnabar jewelry, which will neither cause damage to jewelry nor distinguish between true and false. 1, visual inspection first. The real cinnabar is a mineral, its color is not very bright, and it looks a little reddish. 2. Because the raw ore is purple, the products have different colors because of different particle sizes. Hang a small amount of powder when leaving, including purple, red, red and yellow. The fake resin is white and the lead is black. Adding jade, it feels very transparent, its weight is higher than real cinnabar, and other fake cinnabar is lower than real cinnabar.

Question 3: How can cinnabar distinguish between true and false is mainly these two species and four species for reference.

Fire detection method 1: take a little genuine product, wrap it in tin foil and heat it, the color will turn brown first, then black, and make a crackling sound at the same time; Liquefied into colloid and foamed repeatedly; Long-term combustion does not ash, leaving honeycomb traces after cooling. After the counterfeit money is heated in the same way, there is no other change except that the color changes from dark red to black. Method 2: Put a little genuine product on white paper, heat it under the paper, change it from bright red to black, and leave the flame. The original color is restored, and the white paper is not stained. Fake goods change from dark red to black when heated, and cannot be recovered after leaving the flame, and the white paper is dyed light red. Method 3: Pick a little genuine powder with a matchstick and light it. You can see bright and tiny mercury beads on the burnt matchsticks. Counterfeit products have no such reaction. Method 4: add a small amount of iron powder into the test tube, seal and heat, and form mercury beads or mirrors on the wall of the test tube. After the fake is heated, the tube wall is reddish, and the small particles turn silver gray.

Try to take some real water, put it in a beaker filled with clear water, shake it well and leave it for a while. The water is not dyed and the sediment is dark red. After the counterfeit money is put into the water, the water is dyed light red, most of the sediments are silver gray, and a few are dark red.

Question 4: How can a cinnabar bracelet be distinguished from a genuine one, and how can cinnabar jewelry be distinguished?

Cinnabar is a kind of mercury compound mineral, cinnabar, cinnabar, which mainly contains mercury sulfide, and is a commonly used sedative in important towns. A fake cinnabar has been found, and its characteristics and physical and chemical identification are as follows.

Character recognition of 1

1. 1 Authentic This product is a block or granular * * * body, granular or flaky, bright red or dark red, striped red or dark red, shiny, crisp, flaky, shiny, odorless and tasteless. When the product flies in the water, it is easy to be ground into pieces or particles, and its suspension is vermilion, and there is no residue at the bottom of the mortar.

1.2 counterfeit this product is powdery, dark reddish brown, with a small amount of regular particles, shiny, heavy, firm, odorless and tasteless. The dyed hand at the powder of this product is heated by direct fire, and the dark reddish brown quickly fades into silver-gray powder. When water flies, its particles are not easy to grind and its suspension is dark brown. After draining the suspension, you can see a layer of silver-gray sand.

2 Physical and chemical identification

2. 1 Take 20g genuine powder and heat it in a closed tube. Black mercury sulfide appeared on the tube wall, but when sodium carbonate was added for cooking, metallic mercury balls could be seen.

2.2 20g of powder was also taken from the counterfeit products and put into a closed tube for heating, and no substance appeared on the tube wall.

To sum up, the fake is obviously different from cinnabar in character, and physical and chemical tests show that it does not contain mercury, so it is not cinnabar.

Therefore, when you buy cinnabar jewelry, you should identify it from the above two aspects, or ask someone who knows the product to help you identify it, so as not to be deceived.

Question 5: How to distinguish the authenticity of cinnabar jewelry teaches you to distinguish the authenticity of silver jewelry. 1. If you like, you can draw a silver chain with white wall or white paper to show that most of it is pure silver. 2. Throw the silver one on the table. It sounds boring. It's pure silver, not metal. 3. Generally, regular goods are engraved on jewelry. If it is pure silver, it should be "ag925" or "925". High purity silver jewelry, with yellow in white. 4. Silver forged with copper, brass, white copper, lead, tin, aluminum, etc. Features: copper: purple in appearance, black in stubble and embroidered green. Brass: yellow in appearance, stubble green and embroidered green. White copper: appearance gray, stubble brick gray, green embroidery. Lead: grayish blue, soft, with nail marks. Tin: silvery white, soft, and can be scraped with nails. Aluminum: white gray, soft and light. If it is allergic skin, you will know whether it is true or not after wearing it for a while. -Look at the color: the higher the purity, the whiter the silver, and the jewelry surface looks even and shiny, which has a touch-up effect. If it contains lead, the jewelry will appear bluish gray; If it contains copper, the surface of jewelry will be rough and the color will not be moist. Weighing: The density of silver is slightly higher than that of ordinary metal. Generally speaking, "aluminum is light, silver is heavy, and copper is not light or heavy." Therefore, it can be preliminarily judged whether it is silver by weighing. If the jewelry is large and light, it can be preliminarily judged that the jewelry belongs to other metals. Hardness inspection: the hardness of silver is lower than that of copper, but higher than that of lead and tin. It can be detected by marking the jewelry in an inconspicuous place with a pin. If the needle slips, it is difficult to leave traces on the surface, which can be judged as copper jewelry; If it is made of lead and tin, the trace is obvious; If the object has traces but is not obvious, it can be preliminarily judged as silver jewelry. Listen to the rhyme: hitting the floor, sterling silver ornaments, no elasticity, the voice is "boo boo boo". The lower the color, the lower the sound, and the sharper and higher the rhyming sound; If it is made of copper, its sound is high and sharp, and its rhyme is short and short; If it is made of lead and tin, the sound of falling to the ground is dull, short and inelastic.

Question 6: How to judge the authenticity of cinnabar? Is the cinnabar bracelet bought by 300 yuan true? I'm afraid I can't buy it.

Question 7: How to identify the authenticity of the cinnabar bracelet itself is artificial, how can it be fake? The fake bracelet is plastic.

Question 8: Who can help me distinguish the new cinnabar bracelet from the real one? Cinnabar is a kind of mercury compound mineral, cinnabar, cinnabar, which mainly contains mercury sulfide, and is a commonly used sedative in important towns. A fake cinnabar has been found, and its characteristics and physical and chemical identification are as follows.

Character recognition of 1

1. Authentic products are block or granular * * * bodies, granular or flaky, bright red or dark red, streaked red or dark red, shiny, fragile, flaky, fragile, shiny powder, odorless and tasteless. When the product flies in the water, it is easy to be ground into pieces or particles, and its suspension is vermilion, and there is no residue at the bottom of the mortar.

2. Fake product This product is powdery, dark reddish brown, with a small amount of regular particles. The particles are shiny, heavy, firm, odorless and tasteless. The dyed hand at the powder of this product is heated by direct fire, and the dark reddish brown quickly fades into silver-gray powder. When water flies, its particles are not easy to grind and its suspension is dark brown. After draining the suspension, you can see a layer of silver-gray sand.

2. Physical and chemical identification

1. Take 20g genuine powder and heat it in a closed tube. Black mercury sulfide appeared on the tube wall, but when sodium carbonate was added for cooking, metallic mercury balls could be seen.

2. 20g of powder was also taken out from the counterfeit product and put into a closed tube for heating, and no substance appeared on the tube wall.

This fake is quite different from cinnabar in nature. Physical and chemical tests show that it does not contain mercury, so it is not cinnabar.

When wearing cinnabar jewelry, you should identify it from the above two aspects, or ask someone who knows the product to help you identify it, so as not to be deceived.

Question 9: How to judge whether a spell is true or false? Is it cinnabar? Some are purely ghost paintings, which have nothing to do with the use of cinnabar, while others are harmful.
