My system is not decent

Chapter 664 High quality and high price (seeking subscription monthly pass)

As a big customer, Chen Xingchen was able to buy some bottom tank cleaners through special channels.

This batch of minerals, the most important thing is the bottom tank cleaning, in addition to this, there are two relatively rare minerals, one is dragon's blood sand.

This requires special handling and special use. If you can't use it, then you can't use it.

First of all, there is dragon blood sand, which is certain, it is not something that some people say, it is something made by Dingshan people.

However, the dragon blood sand that Chen Wenzhe and the others bought here is a different concept from the dragon blood sand that most merchants talk about.

Dragon blood sand is a relatively special mineral material in Huanglong Mountain. Why is it special?First of all, its color is very red.

Because the content of iron oxide is extremely high, it looks as red as blood, so it is called dragon blood sand.

In fact, it belongs to the same mineral material as Dahongni, and it is produced 50 meters west of Dashuitan, on the north side of Zisha Road.

When the Zisha Road was excavated, a trough of blood-like ore was found. The ore layer was very thin, only 15 centimeters thick at the thickest part, mixed among boulders.

According to the analysis, the ferric oxide contained in dragon's blood sand is three times that of ordinary purple clay. The firing temperature is relatively low, and many black stars will appear on the surface under high temperature.

Here comes the important point, Dragon Blood Sand is so good, but there is one biggest shortcoming.

Dragon's blood sand is silty mudstone, which is basically granules and has poor plasticity. Even if it is crushed to a high mesh, it is extremely difficult to make.

Here, if you want to take advantage of his bright color after firing, you have to think of a way.

This requires the means of practicing mud. If it is not for the fusion of various skills, Chen Wenzhe would not use this kind of mud.

And the last one is the golden section mud, which is the golden section.

The Jinhuang section mud is produced in the area of ​​Well No. [-] in the south of Huanglong Mountain, at the geological level of the Wutong Formation.

The top is the small red mud, and the next is the golden yellow mud.

This kind of mud is only about 10cm thick and needs to be collected manually and excavated with a small shovel.

Below this layer of golden yellow mud is white pockmarked and purple mud.

Under the compression of the formation, the titanium element of the small red mud permeates into the section mud, and then coexists with the purple mud in the lower layer.

This material has existed before, and it is not a fabrication of modern people.

Duanni is mixed with purple mud (the purple ones), and the purple mud content is very small and very tender.

When using a stone mill, it is broken into small particles and mixed in. After grinding, it is passed through a 50-mesh sieve, and water is added to refine it into mud.

This kind of mud is relatively rare and expensive!

Therefore, there are so many under the banner of the golden section in the market, which is similar to the situation of the blue bottom.

But basically the low-priced ones are mainly chemical materials, and titanium yellow is added. Of course, the foundation is also foreign materials.

This kind of pot, after being fired, turns lemon yellow, which is more dazzling and not soft. The pot is heavy in mud and lacks the feeling of sand.

However, the effect produced by the real golden segment is completely different.

Feel the high-grade mud a little bit, good mud, and poor mud, in Chen Wenzhe's hands, the feeling is different.

It's a pity that no matter whether it's bottom tank clear, dragon's blood sand, or golden section, there are not many of them.

What he has the most here is clear cement, but the clear cement that Chen Xingchen enters is a kind of high-quality mud in the purple sand mud.

This kind of mud is pure purple mud, which is directly aged and processed into mature mud. People in the industry generally call it "general mud", which is a more commonly used mud.

Zisha raw ore slime, which looks like stones, has a flaky structure. After being stored in the open air and weathered for a period of time, it can be decomposed into soybean-sized particles.

Use mechanical processing to crush it to the required fineness, add water to adjust and knead, and then it will become a mature mud.

To fire the purple sand teapot made of this kind of mud, the general kiln temperature is 1160~1180 degrees, and the shrinkage ratio is about 11%.

This is the original color mud of Huanglong Mountain Pass in Dingshan, Yixing. This kind of mud has very good properties.

Easy to handle wet and dry, high stability, reasonable viscosity, easy molding.

Chenni must be smelted, otherwise black edges and flower mud will easily appear.

The characteristic is that the clay color is mellow and elegant, with a strong literati atmosphere, and works of all sizes can show the elegance of purple sand.

To put it simply, it works!
This kind of purple clay teapot becomes more ruddy and patina-filled with time. It is easy to make tea, has good affinity, and the temperature is easy to control, so it can be easily brewed.

After soaking for a long time, it will become more rosy, simple, ancient and dignified.

Yesterday, Chen Xingchen made a batch of clear cement purple clay teapots, and the kiln has already started.

After Li Jinli came to the factory, the first thing he saw was the opening of the kiln.

Therefore, when Chen Wenzhe came to the electric kilns, many electric kilns had already been emptied.

It was a coincidence that he came here, just in time to see a batch of beauty pots made by Chen Xingchen come out of the kiln.

Of course, this is also because Chen Xingchen is the main force, most of the works fired in these electric kilns are his works.

The beauty pot is still the same beauty pot, the outer skin was wiped with clear cement, and it was indeed polished.

It's not a simple flame, but with a little crystal color, which already has the effect of a little precious light.

Picked up a teapot and it looked pretty good.

A good quality purple sand teapot is undoubtedly the pursuit of many teapot lovers.

But many teapot lovers don’t know much about purple sand teapots, and they are afraid that they will buy a defective product after spending a lot of money. Not only will they lose face, but their interest in playing with teapots will also be greatly reduced.

Therefore, recently Yi Nian Tang is also promoting the identification method of purple clay teapots.

In fact, there are many ways to identify purple sand teapots, such as looking at the surface color of the teapot, pouring boiling water, smelling the smell, touching the teapot, rotating the lid, tapping the teapot body to listen to the sound, etc., can all be identified.

Generally learn to judge whether it is a real clay teapot by looking at starlight, melting point, sand color, etc.

Manual traces, seals on the inner wall, and the certificate of the person who made the pot are also relatively simple elements for judging.

How to distinguish handmade pots, locomotive pots, and grouting pots?

In fact, it is also very simple. The locomotive pot is generally made by rotating and pressing a model. From the body or lid of the pot, you can see layers of car marks or uneven lines, which can basically be judged to be a locomotive pot.

For grouting pots, the mud must be made into a very fine "slurry", and more glass water must be added.

Because of this, the section of the grout pot is very fine and has no sandy texture.

And when it is made, the mesh number is very high, and the air permeability is poor, which can be observed by hand touch and visual inspection.

As for the chemical pot, the price is cheap and the color is bright and translucent, but this kind of pot is artificially added with chemical raw materials, such as: manganese oxide, lead oxide and other harmful substances, which are extremely harmful to human health.

Chemical mud, through some deployment methods, can almost achieve the effect of real mud, but the price is less than one-tenth of the authentic mud.

Therefore, if you encounter a purple clay pot that looks good and is cheap, you must be careful.

There must be a reason why people sell it cheaply. In short, no one is willing to do a business that is not profitable!
When Chen Wenzhe was examining the purple sand, Li Jinli leaned over.

"How is it? I think it's fired well, and it can be sold as a real sixth-level handicraft."
