Which is better, the head groove is clear, the middle groove is clear, and the bottom groove is clea

The middle groove is clear. Because it is produced in the middle layer of purple mud, the texture is very pure, the mud is delicate, the quality is firm and delicate and smooth after firing, and the finished product texture is simple and natural, calm and generous. Brew tea with a medium groove, tea soup.

The charm is melodious, the bubble culture changes quickly, the warmth is richer and fuller after the bubble culture, and the tea soup has a melodious charm, the more simple and elegant it is. According to the query of relevant information, Zhongguo Qing (also known as Zhongguo Qing, Zhongsoap Qing), produced in Yixing, Jiangsu.

Huanglong Mountain, which belongs to the purer varieties of purple mud, has less mineral content. Because the mine is usually in the middle of the purple mud layer, it is called the middle groove clearing. The main body of the ore is purple-brown in color, with more white mica fragments.

The raw ore material is only precipitated by water through sieve grinding, and the mud is purple-brown-red. After firing, it is red pig liver color, and white mica particles can be seen in the cross-section.

The head groove is clear, the middle groove is clear, and the bottom groove is clear, and the three have their own advantages.

1.The head groove is clear: the material is more tender, and the corns spots on the ore section are not rounded enough.

2.Zhonggroove Qing: The texture is very pure, the clay is delicate, the quality is firm and delicate and smooth after firing, and the finished product texture is simple and natural, calm and generous.

Brewing tea with the middle groove, the charm of the tea soup is melodious, the brewing changes quickly, the warmth and moisturization after brewing are more rich and full, the charm of the tea soup is melodious, and the more simple and elegant it is.

3.Bottom groove clearing: It exists at the bottom of purple mud, and the quantity is small. After firing, the color of the pot body is deep and full of changes, the texture is delicate, the gloss is good, and the air permeability is good.

All in all, the head groove cleaning, the middle groove cleaning, and the bottom groove cleaning have their own characteristics, and there is no absolute superiority or disadvantage. When choosing, you can choose according to your personal preferences and needs.

The bottom groove is a relatively pure variety of purple mud, with less mineral content.

The bottom groove is a relatively pure variety of purple mud, with less mineral content. The bottom tank was first produced in the No. 4 mine of Huanglongshan, and the No. 4 mine was also the best produced by Zishout, and the other trace cluster was also mined in the No. 5 mine of Huanglongshan and Taixi mining area in the field.

Because it is usually at the bottom of the purple mud layer when mining, it is called the bottom groove clearing.

Bottom groove cleaning is the name of a mineral, that is, purple mud ore with corns.

The pot fired at low temperature is red pork liver color, and the color of high temperature firing is purple and blue, which is very rare. It can be fired at about 1200 to 1300 degrees, and can be fired at more than 1400 degrees. The bottom groove green is produced in Huanglong Mountain, Yixing, Jiangsu.

It was first produced in Huanglongshan No. 4 well, and later Huanglongshan No. 5 well and Taixi mine.

The bottom groove is the mud that belongs to the purple mud category.

The bottom groove is produced in Huanglong Mountain, Yixing, Jiangsu. It was originally produced in Huanglongshan No. 4 well, and later in Huanglongshan No. 5 well and Taixi mine. Purple mud mines can be broadly divided into three categories:

There are three types of mud, such as the head slurry, the second slurry, and the bottom slurry, which is produced at the bottom of the purple mud and has the highest quality. It is the first of the generations of potters, and it is also a classic for hundreds of years, and the most beloved clay of the late Master Gu Jingzhou.

The name of this mud mine, because the local dialect of Yixing has been used for a long time, for fear of confusion, so it is used to translate the text literally, and it is named after "the bottom is green". Because it is produced at the bottom of purple sand, the texture is very pure, the mud is fine, the color is stable, and it is brown. It is widely used by famous modern kettlers.

Many people say that the bottom groove green is a kind of clear cement. This concept seems to have changed a lot after the detailed division of the types of mud today.

Does clear cement have corns? It seems that there are some of them, but they are scattered and uneven. In the bottom trough green mine, the corns are paired, and the distribution is very dense and uniform.

Does the clear cement contain green mud uniformly? This is negative, there is no natural green in the clear cement, unless the later deployment, and the later deployment of the green, after firing, many of the green particles are overflowing, not the concept of purple mud wrapped in the green.

In the past, the most commonly used was the No. 4 well, and now the No. 4 well is rare, so the mine in Taixi (No. 5 well bottom trough green) is used. Judging from some physical observations in my hand, the hair color of the finished product of Taixi Mine is relatively tender and watery, not simple enough, and the hair color cannot reach the dark texture of the high temperature of Well No. 4.

Under the premise that the thickness of the mud embryo is consistent, the finished product of the bottom groove green is heavier than that of clear cement. The reason is that purple mud contains natural green, and the iron content is greater than that of clear cement, so the bottom groove green is heavier than clear cement.

A big difference between the bottom groove green and the clear cement is that after the bottom groove green mud embryo is crushed, it is difficult to form the finished product directly, and the time required to decay is longer than that of clear cement. The bottom groove green is sandy, the sand is extremely strong, and the viscosity between the particles is much lower than that of purple mud, even if it is crushed to 100 mesh, the finished product looks obviously sandy. If a certain amount of tender mud is not allocated, it is difficult to directly form the new bottom groove after crushing.

Under the premise of the same aging time, the refractory temperature of the bottom groove green is higher than that of clear cement. The exact reason is ominous. It is precisely because of the high refractory degree that the bottom groove blue has more changes in mud color than that of clear cement firing, and it is more beautiful.

The hair color of the orthodox bottom groove blue can be red in purple, and the color is dark and simple. And clear cement can't achieve such a color.

The bottom groove clears the bottom groove of the original ore and the finished product is clear: The bottom of the dregs is produced in the Huanglong Mountains of Yixing, Jiangsu, and the purple mud ore can be roughly divided into: the first dregs of the green, the second dregs of the green, the bottom of the dregs of the green, the real name of the mud is produced at the bottom of the purple mud, the quality is good, for the first generations of potters to respect, but also for hundreds of years of classic famous vessels, and the late Gu Jingzhou master Zhong favorite name mud; The name of this mud mine, because the local dialect of Yixing has been used for a long time, for fear of confusion, so it is used to translate the text literally, and the name is "the bottom of the dregs green".

It was first produced in Huanglongshan No. 4 well, and later Huanglongshan No. 5 well and Taixi mine. Mud: Because it is produced at the bottom of purple sand, the texture is particularly pure, the mud is delicate, the color is stable, and it is brown, which is widely used by famous pot makers in modern times.

In recent years, the No. 4 well in Huanglongshan has been closed due to the collapse of the well, and the mineral source has become increasingly scarce, and the residual accumulation and weathering of the "bottom dregs green" have become more and more precious; Yixing purple sand is world-famous, and this mud is indispensable. The kiln temperature is about 1180 degrees C, and the shrinkage ratio is about 12%.

Tea: Mild and elegant, the charm of the tea soup is melodious, calm and long-lasting, and the mud color changes from brown to ancient dark liver color, which is more simple and elegant, bright and bright! It is suitable for making various series of Pu'er tea, oolong tea, raw tea (light roasting series), Longjing, flower tea, Biluochun, black tea, green tea, etc.

Bottom soap green is the name of a mineral, that is, purple mud ore with corns.

In the past, it was the main raw material of Shanghao clear cement. The fired pot presents the color of red pork liver, and the color of the firing depends on the composition of the mineral material and the firing temperature.

There is also a name for the bottom soap: "bottom groove clear", the origin of this name is said to be: the mud is divided into the upper groove, the middle groove, and the bottom groove is the best.

However, there are many questions about this statement, and Mr. Chen Yi once asked the former mine workers, but Du Yun did not know that there was such a statement. However, what is the upper groove, what is the middle groove, and what is the bottom groove, there are different statements, and there are many contradictions. It is believed that the name "bottom groove clearing" may be false.

The reasons are as follows: 1. The mud is not necessarily the better the bottom, and the exposed surface is not without good material.

2. The word "Qing" has no meaning.

3, and the bottom soap blue statement is more reasonable, because the color of the mineral is soap blue. The direct mud of the bottom soap blue ore has relatively high requirements for the firing temperature, so in the past, it was usually added to the sintering temperature or other mud (tender mud) to reduce the sintering temperature, improve the moisturizing feeling of the product, and it can be used to regulate the color when properly controlled.

Note: Shihuang is a natural mineral material, and it is relatively rare in history. It is not that the mud with the addition of stone yellow is not a good mud.

Another: Shihuang and Shihuang mud are not the same thing, Shihuang mud is the current Zhaozhuang red mud. The biggest feature is that it is not easy to hydrate.

Shi Huang: It's not Shi Huang mud. It is the "treasure" in the traditional purple sand mud, and the pure bottom soap green should rely on the stone yellow to "point".

Because the purple clay pot made of pure bottom soap is very "astringent", commonly known as no "water color", adding natural stone yellow can reduce the firing temperature, improve the texture of purple sand, and have a strong sense of moisture. The calambus ore is very much like an egg, with a shell, a mantle, and a core.

About clear cement: clear cement is a mud refining method, which is directly crushed into mud without adding other miscellaneous materials to refine the mud is collectively referred to as clear cement. Qing cement used to be in the first factory, which refers to the low-grade coarse raw materials directly processed from purple mud ore, mainly to make low-grade products and flower pots.

In the late 80s, when high-quality raw materials were relatively reduced, people's aesthetic pursuit of the texture of the original material began to pay attention to the clear cement (purple mud) that was originally used as a road goods product. However, now the clear cement does not seem to have the original meaning, and the purple mud without chemicals can be called clear cement.

Now we usually call the mud refined from pure bottom soap green ore: "bottom soap blue", in fact, the bottom soap blue is a mineral material, and the refined mud is called clear cement, which is in line with the original meaning of clear cement. But now we are used to calling it a soap green (which seems to try to illustrate the purity of purple sand ore).

As for the problem of iron "precipitation" caused by the high-temperature firing of the bottom soap blue ore, as long as it does not affect the appearance of the teapot, it should be acceptable, because this is the mud nature of the natural bottom soap blue. As for the fact that some people currently use strong acid bubbles to wash and clean iron when the base soap is green when formulating, we don't think it's necessary.
