How to distinguish the authenticity of the purple sand cinnabar pot, and the identification method o

Hello everyone, I am the shopkeeper Xu, 72 years old this year, I am not a master, but a craftsman who loves purple sand, plays purple sand, and makes purple sand pots, and is an old craftsman who has been making purple sand pots for most of his life.

My family has been making pots for generations, and I have a small shop in the local area, and I have invited some good local masters to help make pots, and my time and energy are mainly spent on watching the master make pots and taking apprentices, and sometimes I also make pots in the shop.

WeChat is my granddaughter to help me do, young people understand the Internet, typing fast, in order to let more people who like purple clay pots buy pure handmade natural purple clay pots, so we also catch up with the fashion, follow the trend.

Four generations of our family have been making pots, and by the time my granddaughter's generation is the fifth generation. Our local pot family has the habit of storing mud, because to make a good pot you have to use good materials, in addition to weathering, good materials have to be aged for about 3 years, so our family has always stored a lot of mineral materials, and there are a lot of good materials that are stale. Our pot is made of these old materials, to ensure that the real purple sand is refused, and chemical materials are refused.

Other people may have the same pot type, but you will definitely not find such a good purple sand mud as ours outside.

Helping pot friends buy authentic and good purple clay pots is self-cultivation and self-cultivation, accumulation of blessings and virtues. I also hope to help everyone understand the purple sand and fall in love with the purple sand, you can follow my WeChat, more**, whether you choose our purple sand pot or not, I hope that the purple sand knowledge in the store can help you choose and distinguish the real purple sand.

But many enthusiasts look at the vermilion purple clay pot like seeing flowers in the fog, so what is the real vermilion purple clay pot?

1. Weigh the weight, usually pay attention to the approximate types of various muds, although there are differences in their respective muds, but they have a feel after a long time, which is very accurate, this item is more difficult for entry-level students, but this road must go.

2. Observe carefully, the purple sand must have a sense of sand, smooth like porcelain do not need to look at it anymore, in addition, particularly bright, or particularly bright pots are far away, the real purple sand has been implicit color and reflection, it is worth mentioning'Yes, a large number of "vermilion pots" are mixed with iron red powder to make red, this is not a very good way, see more and learn more, after a long time, you will understand the color of iron red powder, you can naturally distinguish, add a sentence, there is a kind of deceptive method is spraying slurry, that is, spraying a layer of good material on the surface of the poor material, to observe more, especially to listen to the sound, observe the inside of the pot.

3. Smell the taste, the unused purple clay pot has a unique Saturn smell, really smell too much, and you can know it when you smell it.

4, look at the water absorption and air permeability, their respective mud species, only the water absorption and air permeability of the vermilion mud is slightly poor, the test method is roughly as follows: at least two days have not touched the water of the pot, boiling water is added to the pot, the ears are close to listen, you can hear a very obvious water absorption sound, and even can see small bubbles keep rising to the surface, boiling water poured on the body of the pot, you will find that the water and the pot are very close, if the water is very fast to row away, wipe it with the leftover tea leaves, or so, the mud is suspicious, the purple sand basically the water will be wet wherever the water goes, and it does not slip away, When the pot is not poured into the boiling water, wipe the body of the pot with your fingers dipped in water, and you will find that the purple sand and water are very close, try it to know.

5. Pour boiling water into the empty pot, and then flush the lid of the pot, the water level of the spout of some pots keeps popping, but it is not that there is a problem with the pot that does not behave in this way, which has a great relationship with the shape.

6. Look at the color of the water, many good materials (except vermilion mud) are poured into boiling water and then poured over the pot after the color changes slightly because of the water absorption, and the false purple sand does not have this change, observe more.

7. Listen to the sound, the sound of purple sand is flat, the sound is slightly sharp (the sound of vermilion is slightly sharp, the sound is similar to the sound of gold and stone), the sound of other clay is dumb, and the sound of hand-drawn blank and grouting pot is sharp because of the addition of glass water (much sharper than the sound of vermilion), close to the sound of glass, listen to it more, and soon feel it.

8. Soaking and raising, good material soaking and rearing must change, and the surface slowly appears slurry, and the color is getting more and more moist. This change is not noticeable or pleasant.

Introduction: The so-called raw ore vermilion refers to the crushing of the vermilion mud ore with a certain number of mesh (usually 40 or 60 mesh sieve, 80 mesh is very rare) sieve after screening, adding water and making and stale, without adding any other substances. The slurry slurry is usually made of ore with more impurities (that is, not pure enough) to sand powder the required mesh first, and then flushed into a very fine slurry (usually 200-300 mesh), so that the fine slurry will be used to cover up all impurities.

The following brings you the identification method of real and fake vermilion pots, come and take a look.

There are more than a dozen types of vermilion, with different colors and shrinkage rates. According to the mud refining process, it is divided into two processes: pure material and sand mixing, pure material: the most difficult to fire, the deformation coefficient is very large, the firing product is oily, the color is bright, the texture is delicate, and the feel is excellent.

Sand mixing: It is to grind the cooked cinnabar mud into particles of different mesh sizes and then add the pure vermilion mud to the secondary firing, which reduces the shrinkage rate of the mud, and the firing is easy to form, the style is relatively coarse, and the old taste is enough.

The counterfeit vermilion pot is mixed with vermilion mud in clear cement or small red mud, the density of the mud is much smaller than that of vermilion, and there is also the luster of vermilion, but the gloss is much worse and cannot be cultivated.

At present, the market price of pure vermilion mud, more than 1,000 yuan a catty, the yield of firing vermilion mud, the highest is only 30%, to make a medium-grade vermilion pot, you need half a pound of mud, plus 70% of the scrap rate, a total of one and a half pounds of mud are needed, so the cost of a vermilion pot will not be less than 3,000, plus the circulation profit of the dealer, the sales price of the vermilion pot made by arts and crafts artists is close to 10,000 yuan.

Moreover, the mud of the big red robe does not exist, and the big red robe is only the color of the vermilion mud that is fired to the limit temperature'A metaphor. The vermilion clay that burns the color of the big red robe is uncontrollable by man, and it depends on luck to burn it, and hundreds of pure vermilion pots can also burn a few handfuls of the color of the big red robe.

Features of the real vermilion pot:

1. The color is orange-red;

2. The mud is irregularly wrinkled, and it is not obvious if you don't look carefully. The high shrinkage nature of the vermilion clay or the wrinkles presented by the mortar ratio are flat on the surface of the pot, but there are many fine, tight and natural shrinkage on the surface of the slurry when examined from the side, which is beautiful and makes people love it.

Features of fake vermilion pots:

1. It will change color after entering the water;

2. Excessive redness, with iron red powder;

3. The mud is wrinkled, it is a regular wrinkle, and the spout and the handle do not have the same texture. Because when he was a mud tire, he was wrapped in toilet paper before the kettle was treated, which is also called toilet paper texture.

1. White paper heating method, the real purple gold cinnabar is placed on the white paper to heat the color to become black source Hu silver, while the fake purple gold cinnabar heating color will not change; 2. Wrap it in tin foil and heat it, the color of the real purple gold cinnabar turns black and makes a popping sound, while the fake purple gold cinnabar has no other reaction except for the color turning black; 3. If the purple cinnabar is placed in the water, the real purple cinnabar water will not be dyed, while the fake purple cinnabar will dye the water light red. Cinnabar, also known as Cinnabar, Dansha, Chidan, and Mercury Sand, is a mercury sulfide (HGS) mineral. Contains mercury, which is the most important mineral raw material for mercury refining; Its crystals can be used as an important material for laser technology.

It is also a Chinese herbal medicine, which has the effects of sedation, soothing and sterilization. Ancient China used it as an important raw material for alchemy. In the past, it was named for the best quality produced in Chenzhou (now Yuanling, Hunan and other places).

The crystal belongs to the trigonal crystal system, which is homogeneous and polymorphic with the black cinnabar of the equiaxed crystal system. often rhombohedral or short cylindrical; It is common to run through bicrystals. Complete cleavage with parallel cylinders.

The aggregates are granular, lumpy, or epithelial. Mohs hardness, the specific gravity color is often red, the crystal surface has red streaks, translucent. Pure cinnabar is diamond luster, vermilion; When it contains impurities, it has a dull luster and is maroon-red.

It is a typical low-temperature hydrothermal mineral, which is related to modern volcanism. China is the main producer of cinnabar, and the production areas are mainly Xinhuang in Hunan and Tongren in Guizhou. Other production areas in the world include Almaden in Spain, Uderio in Italy, and the coastal mountains of California in the United States.

The crystal shape is plate-shaped or columnar, interspersed with double crystals. Hail feast cleavage development. The hardness is small, the specific gravity is larger, the powder of the ghost fairy cinnabar is red, it can not fade for a long time, and China has a long history of using cinnabar as a pigment.

"Painting vermilion oracle bones" refers to grinding cinnabar into red powder and coating it into the notches of the oracle bone inscription to show eye-catching, which happened thousands of years ago; "Zhubi Imperial Approval" refers to the approval written by the emperors of feudal society using the red powder of cinnabar, in order to look eye-catching and preserve it for a long time.

There will be some natural wrinkles on the inside and outside of the vermilion pot, which are shaped like pear skin lines, water ripples and dotted lines. Fake wrinkles are basically applied directly to them with toilet paper, so they don't look very natural, and there will be spots on the paper. There may even be some visible marks left on the surface that are uneven.

01 The vermilion pot has excellent water absorption, and the surface of the pot can also hang water, if it is a fake vermilion pot does not have the characteristics of water absorption, the water absorption is relatively poor. Generally, after being drenched, the surface can not hang water droplets at all, and there will be oil droplets on the surface after opening, which is generally fake.

02 The shape of the vermilion pot is not particularly neat, and it will generally have defects, but a certain part will be more unique, and each different vermilion pot will have a different appearance and character. But if it is fake, most of the shapes are not neat, and at the same time, it will be very ugly.

03 The vermilion pot has excellent resonance, and you can feel a slight vibration by gently flicking it with the index finger of your right hand. But if it's fake, there's no resonance at all.

04 You can also use the method of percussion, which generally has a strong texture after percussion, and will also have a sonorous and pleasant sound, as if the sound of jade and jade colliding. But if it is a fake vermilion pot, when it is struck, there is generally a sound of iron and iron striking.

The method of purple cinnabar to distinguish the real from the fake: weight, feel, color, surface texture, luster, and section.

1. Weight. Real cinnabar is very heavy, and it will feel like a pressure on the hand when placed in the hand. And some fake cinnabar is made of plastic, which is light and fluttering in the hand, sticky to the touch, and has a strong plastic feeling.

2. Hand feel. The cinnabar texture of Zhenqichai is warm and delicate, giving people a feeling like jade, and at the same time, the surface will have a certain degree of luster. And the fake cinnabar texture is rough and dry, and it doesn't feel good in the hand.

3. Color. True cinnabar is natural and flexible, mainly bright red or maroon, and impurities will appear on its surface, and the color is layered. The fake cinnabar is bright in color, and the color gives people the feeling of floating on the surface, and it is easy to fade.

4. Surface texture.

The surface texture of real cinnabar is coarse, the grain distribution and color are not very uniform, and it contains black or white impurities. The surface texture of the fake cinnabar is too evenly distributed, which appears very regular and looks flawless.

5. Luster. The surface gloss of real cinnabar is very good, and the luster of diamond is the main one. The false cinnabar has a rough texture, many internal impurities, a dull surface luster, and a resin luster next to the cherry blossoms.

6. a section. The cross-section of true cinnabar has distinct crystalline grains that look like sequins or highlights with a metallic sheen. False cinnabar has no crystalline grains in cross-section and is very ridged and smooth.
