question 1: my family has a pair of purple clay pots made by Cai Yan, whose works are red and black clay crystals, but generally speaking, black clay pots are all chemical pots. What do you think of Zhao Zhuang's original clay is the best of all clay pots? It is characterized by its greater shrinkage than ordinary clay pots, so the pot body has obvious water marks, and the spout and handle burned are generally deformed, so it is generally pure Zhao in the market.

There are two main situations in which the bamboo clay pot is burnt black. One is the lack of oxygen in the kiln, which causes the pot body to turn black, but this situation is mostly local black, and the whole pot is rarely black (this is the so-called bamboo clay kiln-changed pot). The other situation is that manganese oxide is added to the bamboo mud, and the pot burned is similar to what you described, but this pot has been fired at a high temperature of more than 1 degrees, which is harmless to the body.

All the surface layers of Zhu clay pots are knocked off with sandpaper, and the inside is black. This black is the so-called crystal. I wonder if you mean this red and black crystal.

question 2: who knows about black ink mud? Well, I've heard that black vermicelli is fired at a high temperature of more than 12 degrees, but after my understanding, the vermicelli pot is very sensitive to the firing temperature. The temperature between the mature temperature of clay and the solid vitrification is very narrow, about 1 degrees. Before the pot arrives, the color of the pot body is dull, and the skin is dry and loose. No matter how you raise it in the future, you can't raise a full and sweet red color. After that, the skin of the pot deteriorates. In a slight case, there is a little bubbling inside the pot body and the bottom of the pot, and the pot body has a slightly melted and inclined posture, which has no aesthetic feeling at all; What is serious is that the whole kettle body bubbles, the kettle body collapses, and the carcass structure becomes spongy and all scrapped. Therefore, if it is vermicelli, there is no such thing as a high fire vermicelli clay pot. So it's hard to judge.

Question 3: How to distinguish the authenticity of clay in teapot? (1) Purple sand is a porous material with double pore structure, with fine pores and high density. Making tea in a teapot does not lose its original flavor, and the fragrance does not linger, so that the tea is really fragrant and delicious. "Chronicle of History" says that it "neither captures fragrance nor smells like cooked soup".

(2) the teapot has good air permeability, so it is not easy to spoil the taste of tea when used, and it will not spoil in summer. If you don't use it for a long time, there will be no odor. Just store boiling water first, pour it out immediately, and then soak it in cold water for washing, and your vitality will be restored, and the tea will still have its original flavor.

(3) the teapot can absorb tea juice, and the inner wall of the teapot is not brushed, so there is no peculiar smell when making tea. After long-term use, the teapot wall accumulates "tea rust", so that the empty teapot will be filled with boiling water, which is related to the certain porosity of the teapot embryo, which is the unique quality of the teapot.

(4) The teapot has good cold and hot sudden change performance. When boiling water is injected into the teapot in the cold winter, it will never burst due to sudden temperature change. At the same time, the heat transfer of sand is slow, and it will not be hot after making tea. But also can be placed on a slow fire for cooking and heating, and will not be cracked by fire.

(5) The longer the purple sand is used, the brighter the color of the pot body will be, and the charm will be Wen Ya. If the teapot is used for a long time, the body will become more smooth and lovely because of touching and wiping, so Wen Long said in "Tea Notes": "Love is like palm beads. It has been used for a long time, and it is like purple jade outside, and it is like a blue cloud inside. " "Yangxianming Pot System" said: "The pot is used for a long time, and the mouth is washed and wiped, and the spontaneous dark light is visible." .

question 4: the black vermilion teapot I bought today. To tell you clearly, Yixing Zisha has no such material as black vermilion. It's the seller's name again. Zhu Ni Zhu Ni, Zhu is red, so why add a black one? Purple clay The black clay is called black clay and black clay, so you should evaluate the picture!

question 5: how to tell whether a purple clay pot is vermilion, purple clay or mud? How to distinguish purple clay?

Good clay is basically inseparable from soft color, strong texture and distinct layers. There is only one trick to distinguish clay by soaking and keeping it warm. "Read more and learn more." Green mud, black mud and brightly colored mud are mostly chemical mud. It must be pointed out that the ash-covering pot looks black, but it is not mud, but an ancient decorative craft. The second point: cobalt oxide was added to the early dark green mud of No.1 factory, but it is a very good mud with high appreciation and very expensive price.

question 1: a piece of mud is a lump of mud.

question 2: Zhu ni has many fancy names, such as pear skin Zhu ni, water grain Zhu ni, dahongpao, little red robe, yellow Zhu ni, black Zhu ni, red core Zhu ni and so on. These names for Zhu Ni didn't exist at all before. These vermicelli are the products of modern mixing or processing of vermicelli. Some pure vermicelli is added with stone yellow, some is added with iron red powder, some is added with chemical raw materials, and some effects are made on the surface of the pot, and each effect is given a nice name, perhaps to distinguish it, but it is easy for pot lovers to confuse the concept of vermicelli and complicate simple things.

If we want to simplify things, we just need to divide the vermicelli into several types:

The first type: raw ore vermicelli. The raw ore vermicelli produced in Huanglong Mountain is prepared without adding any chemicals or mixing other mud. (I recommend this kind of vermicelli, firstly, it is healthy, and secondly, it has obvious characteristics and is relatively stable)

The second kind: old vermicelli. Old vermicelli is the vermicelli that has gone through a period of stale time, and it has all the characteristics of the original ore vermicelli. The only difference is that the look and feel of the pot is slightly different, not that making tea will be more mellow. There is a reasonable time limit for stale time, not the longer the better.

the third kind: Zhao Zhuang's little red mud. Xiaozhuang Xiaohong Mud is a title of Zhuni produced in Zhaozhuang by clay practitioners in the past. Its characteristics are slightly different from that of the original ore vermicelli, and the difference is that its shrinkage rate is smaller than that of the original ore vermicelli.

the fourth method: mixing vermicelli. It will be much easier to classify all the fancy-named Zhu Mud into this category, and then study these Zhu Mud with this beautiful name after you have a certain understanding of the first three kinds of mud in the future.

the blind spot of Zhu mud:

1. The difference between Zhu mud in Ming and Qing Dynasties and modern Zhu mud

The ancient Zhu mud and modern Zhu mud were mined from the same source, and they only formed in the earth's crust for thousands of years, so there is no reason why Zhu mud more than 1 years ago is better than the one mined now. Zhu Ni in Ming and Qing Dynasties is superior to modern Zhu Ni only because it has more historical significance. (This view remains to be verified by myself! )

2. No ink and no wrinkles

This view is wrong! After reading Zhu Ni in Ming and Qing Dynasties, we will find that this view is untenable.

3. There is a right and wrong view that vermilion is red and yellow

. First of all, the color of the finished product will be different with different mine sources, stale mud and different kiln temperatures. Yellowing in vermilion red is not necessarily true vermilion, and not yellowing is not necessarily false vermilion. Because many players don't have the standard device of vermilion, even if they do, it is impossible to have one for each color. Due to the lack of their own knowledge, they will go into the misunderstanding of imagination, and the truth is not clear. In fact, as long as we remember the characteristics of mud, we won't be fooled by these things.

there are basically three kinds of sludge: raw ore sludge, old sludge and blended sludge.

the old slime is the slime of the original ore after a certain aging time. Gold section, sesame section These are mixed section mud, for example, sesame section is made by mixing purple mud particles into the green mud of this mountain.

The main purpose of mixing sand and mud is to highlight the texture of mud, which has been liked by many players in recent years. The key is to see the effect of mixing, and whether you like it or not.

Mud materials are generally divided into three series, namely purple mud, red mud and Benshan green mud. All the mud materials can not be separated from these three main mud materials. Clear cement belongs to purple mud category, Zhu mud belongs to red mud category, and the mud in Qinghe section of the bottom trough is * * * raw ore.

Ancient copper mud is a poor mud. This kind of mud will not produce any effect when raised, and it is generally only used for ornaments. Now good ornaments are no longer made of ancient copper mud.

Introduce "red dragon skin" and "slope-dropping mud"

Simply speaking, red dragon skin is a kind of purple mud.

Slope-dropping mud is mud produced between Huanglong Mountain and Qinglong Mountain, which is very suitable for soaking oolong tea. Compared with Zhu mud, it is slightly inferior in fragrance, but more remarkable in charm. This kind of mud is brittle and fragile.

is this the right way to understand mud?

First, the raw ore is made from purple mud or Benshan green mud, which can be made into pots after being picked up.

Second, the synthetic mud is made from purple mud and Benshan green mud, which is currently in the market ...... > >

Question 6: My family has a pair of purple clay pots made by Cai Yan, whose works are red and black clay crystals, but generally speaking, black clay pots are chemical pots. What do you think of Zhao Zhuang's original clay is the best of all clay pots? It is characterized by its greater shrinkage than ordinary clay pots, so the pot body has obvious water marks, and the spout and handle burned are generally deformed, so it is generally pure Zhao in the market.

There are two main situations in which the bamboo clay pot is burnt black. One is the lack of oxygen in the kiln, which causes the pot body to turn black, but this situation is mostly local black, and the whole pot is rarely black (this is the so-called bamboo clay kiln-changed pot). The other situation is that manganese oxide is added to the bamboo mud, and the pot burned is similar to what you described, but this pot has been fired at a high temperature of more than 1 degrees, which is harmless to the body.

All the surface layers of Zhu clay pots are knocked off with sandpaper, and the inside is black. This black is the so-called crystal. I wonder if you mean this red and black crystal.

question 7: who knows the black ink mud? Well, I've heard that black vermicelli is fired at a high temperature of more than 12 degrees, but after my understanding, the vermicelli pot is very sensitive to the firing temperature. The temperature between the mature temperature of clay and the solid vitrification is very narrow, about 1 degrees. Before the pot arrives, the color of the pot body is dull, and the skin is dry and loose. No matter how you raise it in the future, you can't raise a full and sweet red color. After that, the skin of the pot deteriorates. In a slight case, there is a little bubbling inside the pot body and the bottom of the pot, and the pot body has a slightly melted and inclined posture, which has no aesthetic feeling at all; What is serious is that the whole kettle body bubbles, the kettle body collapses, and the carcass structure becomes spongy and all scrapped. Therefore, if it is vermicelli, there is no such thing as a high fire vermicelli clay pot. So it's hard to judge.

Question 8: How to distinguish the authenticity of clay in teapot? (1) Purple sand is a porous material with double pore structure, with fine pores and high density. Making tea in a teapot does not lose its original flavor, and the fragrance does not linger, so that the tea is really fragrant and delicious.

After long-term use, the teapot wall accumulates "tea rust", so that the empty teapot will be filled with boiling water, which is related to the certain porosity of the teapot embryo, which is the unique quality of the teapot.

(4) The teapot has good cold and hot sudden change performance. When boiling water is injected into the teapot in the cold winter, it will never burst due to sudden temperature change. At the same time, the heat transfer of sand is slow, and it will not be hot after making tea. But also can be placed on a slow fire for cooking and heating, and will not be cracked by fire.

(5) The longer the purple sand is used, the brighter the color of the pot body will be, and the charm will be Wen Ya. If the teapot is used for a long time, the body will become more smooth and lovely because of touching and wiping, so Wen Long said in "Tea Notes": "Love is like palm beads. It has been used for a long time, and it is like purple jade outside, and it is like a blue cloud inside. " "Yangxianming Pot System" said: "The pot is used for a long time, and the mouth is washed and wiped, and the spontaneous dark light is visible." .

question 9: the black vermilion teapot I bought today. To tell you clearly, Yixing Zisha has no such material as black vermilion. It's the seller's name again. Zhu Ni Zhu Ni, Zhu is red, so why add a black one? Purple clay The black clay is called black clay and black clay, so you should evaluate the picture!

Question 1: Is the cross section of the Zhu Mud Cup black after it is broken? If it is not black, it is a fake cup. Can the chemical cup be tested by pouring hot water after it is opened? 2 points must first be determined. Purple clay is only found in Dingshu Town, Yixing, and it is not called purple clay in other places, but purple pottery or purple mud at most. Secondly, the simple way to distinguish a chemical kettle is to ask if there is any strange taste, such as sweetness, bitterness, fragrance, etc., and look at the color if there is any problem with the taste; There is something wrong with the enchanting.
