How to distinguish the quality of purple sand mud?

Purple mud and purple mud eat ore with high fire temperature, and the color is reddish when burned. After soaking, it looks like red mud. But the texture is stronger than red clay.

Purple mud is one"Pan"Conception. Bottom saponite is also a high-quality mineral material in purple mud ore. Clear cement originally refers to the mud formation method.

Now it does refer to the purple mud without other ingredients. The soap green without other materials can be clear cement.

Look at the density. The different densities lead to different weights of purple clay pots of the same volume. The different contents of various oxides and proteins in the minerals lead to different densities of the fired purple sand, and the clay like purple sand is heavier, while the real purple sand mud will form aggregates and bubbles in the inner wall structure after firing, so the density is slightly smaller and the upper hand is slightly lighter.

Look at the texture. The purple sand pot fired by the real purple sand mud is like bean paste, no matter how fine the purple sand looks like it still has a semi-suspended granularity, it will not be too smooth to the touch, but it will not hold hands, the purple sand-like clay feels astringent to the touch, and the one mixed with chemical raw materials is too smooth.

Listen to the sound. Purple sand is different from porcelain, without special glazing, after sintering, the surface will naturally form a "mud door" slurry skin with a sense of adhesion, which is not leaky but breathable, and the sound conduction is not as crisp as porcelain, but it is not stuffy, while the purple sand clay is stuffy.

Look at the color. The color of the real raw purple sand mud is dull and the surface is slightly frizzy. If a purple clay pot is bright and shiny, it is most likely that it is oxide or polished.

1. No matter how fine the real purple sand mud is, it still looks grainy, although it is grainy but very round, and it will not be too smooth to the touch and will not scratch your hands.

2. The purple sand pot made of good purple sand mud is not bright in color and greasy, and it must have the texture of jade sand and texture.

3. The purple clay pot made of good mud has a little earthy smell, which is why the new pot needs to be boiled.

4. The purple sand mud made of good mud is dark and elegant, and it will not be very bright, and the good mud gives people a simple feeling.

5. Even if the number of meshes is large, the pure purple sand mud will have a warm and granular feeling, but the mud with chemical industry will give people a smooth feeling.

Purple sand mud is the main raw material for making all kinds of purple sand utensils, produced in the Huanglong Mountain rock layer hundreds of meters below the mud layer between the mud layer, purple sand mud has many classifications, the common red mud, the big red mud, the mountain green mud, white hemp mud and red hemp mud, etc., the purple sand pot made of purple sand mud is the favorite of tea lovers, with the purple sand pot to make tea can highlight the fragrance of the tea soup, long-term use, the wall of the pot adsorbs tea gas, directly add boiling water will also have the aroma of tea, therefore, The best purple clay pot is loved and sought after by people, so how to identify the quality of the purple clay pot? The key is to identify the quality of purple sand mud, and the following will introduce the method of identifying purple sand mud.

1. Look at the color

The pure texture of the purple sand mud color is mellow, rich, slightly dull, no matter what color, the surface of the purple sand pot made by it seems to be smeared with a layer of oil, and the more it is polished, the more it is rubbed, and the color of the purple sand pot made of pure or non-purple sand mud is mostly bright and bright, and there is no mellow feeling.

Second, look at the density

The density of the real purple sand mud is smaller, and the purple sand pot made of it is lighter, and there are bubbles inside the wall of the pot, while the side of the purple sand pot made of clay similar to purple sand feels heavier, and the surface of the body is slightly rough.

3. Listen to the sound

Brew tea in the purple sand pot, after adding boiling water, there is a dull and hoarse sound in the pot, which means that the air permeability of the mud is good, and there is no crystallization inside, this is the real purple sand mud, this purple sand pot is not easy to change the taste, and can also maintain the aroma of the tea, if it makes a crisp sound after injecting boiling water, it means that the purple sand mud is not pure or counterfeit.

Fourth, smell the smell

The purple clay pot made of real purple sand mud has no peculiar smell after brewing tea, and the tea soup will not change color, if it is an impure mud or a mud with added chemical materials, there will be a peculiar smell after brewing tea, and the tea soup will change color after a long time.

Fifth, by feel

The real purple sand mud is very delicate, the appearance of the purple sand pot made of red bean paste is as fine, the hand feels delicate and round, and the clay of the purple sand mud has a heavier astringency, and the mud mixed with chemical raw materials is too smooth, the purple sand pot made of real purple sand mud will become more and more simple with the use of time for a long time, more and more heavy, and more charming, while the purple sand pot made of other raw materials does not have this effect.

There are a lot of all kinds of purple clay pots on the market, in order to choose a good purple sand pot, in addition to the above five points, we should also pay attention not to choose products with surface waxing, now many businesses in order to look beautiful, often wax the purple sand pot, this kind of purple sand pot is generally not a good pot, and there is no collection value, we must carefully identify.

Purple clay pot mud identification method:

1. Color, the first thing to identify the mud of the purple clay pot is to observe the words and colors, the real purple sand pot is probably the color of the view is calm, not glamorous and not greasy, although there is a certain luster, but it should be faintly like a mist, from the inside out, not a thief light. The surface sand is obvious, there is a sense of layering, the particles are looming, and it is fine but not greasy to caress by hand, not scratching hands, and not sticking to hands.

2. Smell, the teapot mixed with chemical raw materials has a peculiar smell, or after making tea, the tea changes color or has a peculiar smell, fades, etc., it is a chemical purple sand pot, a real purple sand pot, and there will be a muddy smell at the beginning of use.

3. Touch, the hand induction of the pure purple sand pot is smooth and round, comfortable and natural, although there are particles, it is still very round, in fact, through long-term soaking, good purple sand can show a deep, simple, oily temperament, and the non-purple sand or purple sand impure pot can basically not be raised.

4. Soaking effect, good purple sand, through the pot to make a little tea, and then used for cloth dry erasing, you can see the matte color, oily is very heavy, the longer the time to raise, the deeper the color quality, simple, until the production of the pot of aura, and people through the temperament.

The mud of the purple clay pot is mainly divided into three categories, namely purple mud, red mud and green mud, which will be subdivided into many kinds after being blended.

1. Purple mud: Purple mud is an interlayer of the nail mud ore layer, the appearance color of the raw material is purple, purple-red, and light green spots, and the appearance color is purple, purple-brown and purple-black after firing. The main component of purple mud is mica, and contains unequal amounts of kaolin, quartz, mica chips and iron, etc., with strong plasticity, high strength of mud blank, and small drying shrinkage, which is the main mud material for making purple clay pots.

2. Red mud: Red mud is a mud material located at the bottom of the tender mud and ore layer, containing extremely high iron oxide, and the body of the pot will change to cinnabar color, cinnabar purple or begonia red after firing. The molding process of red clay is difficult and the output is small, so it is generally used as cosmetic soil to decorate on the purple sand mud blank.

3. Green mud: Green mud is the grease in the purple sand mud, which is known as "mud in the mud". The mud is more tender, and the fire resistance is lower than that of purple mud, and it is generally used for powder or coating on the outside of the fetal body.

<> purple sand mud can be roughly divided into three categoriesThat is, purple mud, red mud, green mud.

among othersDescending mud and section mud belong to natural symbiotic mines, the slope mud and the mud, red mud symbiosis with a little purple mud, the proportion of different mud in each mineral material is different, mainly dividends and yellow slope.

As shown in the figure above, the color of the pot is red and yellowish, and the particles are rich, which is the slope mud.

As shown in the picture above, the color of the pot is purple-brown, which is purple mud.

As shown in the picture above, the color of the pot is yellow, which can be judged to be a mud system.

The same mud will also show different shades and colors at different temperaturesTherefore, it is one-sided to determine the mud by color alone, and it also needs to be combined with the firing temperature, particle texture, metal color, etcThe color should also be based on natural light.

There are three forms of symbiosis between purple mud and red mud, symbiosis between purple mud and green mud, symbiosis between red mud and green mud, and even three forms of symbiosis between mud and materials.

The grade of mud is more expensive than this mountain mud, followed by raw ore mud and blended mud, and the outer mountain material is light.

Ben Mud. Benshan refers to Huanglong Mountain, so the mud produced by the Huanglongshan mining area is Benshan mud.

Raw ore mud refers to the ore material is ground into powder and refined into mud without mixing.

In some cases, in order to make the mud better, it is necessary to add some sand to the mud, or other mud to improve the quality of the mud, so that the mud formed by the mixture is called the mud mixture.

Outer landslide is a concept relative to this landslide, which generally refers to the mineral material in the mining area outside Huanglong Mountain, which is the outer landslide.

For example, Taizhou, Zhejiang, Ningguo, Anhui, these places also have mineral materials, and they belong to the outer mountain materials. Although it is also named after purple sand, its characteristics are very different.

In fact, mud and tea are the same, the essence of good and bad have a common standard, not you have to drink all the mountains to understand Pu'er, as long as you grasp the main characteristics, then you can get through.

No matter what kind of mud it is, how bizarre the name is, and how bizarre the story is, the general criteria for judging its merits are the same.

First, the color should be alive.

The color is natural, the color is layered, and the color of the body will also change with the change of light. A good mud color is subtle, not as dazzling as red and green.

Second, the texture should be moist.

The jade texture is often said to be like jade, which comes out from the inside, rather than the glass light and thief light floating on the surface.

3. Sand is bone, pulp is meat.

A good mud is that the meat is wrapped in the bone, the bone supports the meat, and the sand and pulp are naturally integrated. Can't sand be sand, slurry is slurry.

Zisha plays with sand, but not the more sand, the better. The pot full of sand loses its warm texture, and it is too much.

Fourth, it feels comfortable.

Good mud feels like touching people's **, it feels soft and elastic, and a little sticky. The poor mud feels very hard and rough.

Fifth, the sound has a sense of clay.

The purple clay pot is useful for percussion, but it cannot be classified as simple as stuffy and brittle, and needs to be combined with certain theory and experience.

The above criteria must be taken together, and cannot be inferred from just one of them.

In fact, it is difficult to integrate these points, such as natural color, which is only qualitative and not quantitative, it is difficult to measure with data, and everyone's feeling standards are different. To learn, you have to walk into it, touch it, and not just stop at theoretical knowledgeYou have to try whether it's good or bad, true or false, and you can only make progress with comparison.

Summary. Kiss, there are four ways to distinguish the quality of the purple clay pot mud, 1A look at the mud color There are three main types of mud in purple sand: purple mud, green mud and red mud.

Due to the different proportions of mud, you can also get cinnabar purple, maroon, begonia red, etc., so purple sand mud is also called "five-color soil". There is no definite method for which mud color is best, but it must be noted that some mud is mixed with a lot of fossil fuels, and harmful substances may leach out during use.

2.Second, look at the texture effect Since the purple clay pot is generally not glazed, it all depends on the plain face and plain heart, so the texture effect has become one of the appearance criteria for selection. Some are as delicate as a baby's, and they are full of love; Some are mixed with clinker in the raw material, and after firing, the effect of orange peel appears on the surface of the pot, which is childish and cute.

3.Three look at the plastic art There are two main categories of purple clay pots: one is that the flowers are made by means of deformation and exaggeration.

4.The fourth is light goods, that is, different geometric shapes as the basis for modeling.

Experience. Through the accumulation of time and the exchange of mud refining. There's a lot to see. You can understand the good and the bad. Don't listen to other people's nonsense. Now all handmade pots can be faked. What's more, a mud ratio?
