Chapter 319 Mud is also a baby

"That's right. Zisha teapots are different from porcelain. They pay attention to glaze color and temperature. It's very simple, without glaze, and the temperature is relatively fixed. It all depends on the handicraft and clay."

"The so-called purple sand clay is actually three types of clay: purple clay, cinnabar clay, and Benshan green clay, and purple clay is the main one. All three clays can be made into pottery alone, and can be mixed with each other to make different colors!"

"The mud excavated from the mine is similar to rock in appearance. It cannot be directly swollen with water. It can be weathered into fine particles after being stale. The traditional processing method is to crush and sieve with a stone mill, add water and mix it, and then turn it manually. It is hammered again until it reaches the ideal plasticity to make the finished mud! Now it is crushed with a ball-throwing Raymond mill, and after sieving, it is mixed with water and made into a finished mud through a vacuum mixer!"

Xu Sihai picked up a pot and said: "Look at this pot, the standard Zhaoshanzhuang red mud is the raw mud selected from the Shihuangnen mud mine in Zhaozhuang Mountain, Dingshan, Yixing City. It contains silicon dioxide, quartz and many other special natural mineral ingredients. Zhuni is definitely a good mud. Zhaozhuang Old Zhuni is selected and refined from the essence of "Huangshihuang" at the bottom of Zhaozhuangshan's tender mud mine; the appearance is coffee black, with The texture has been through vicissitudes, the color is vermilion but not coquettish, and it has been used for a long time to reveal the ancient atmosphere, so it is named after the place of origin, and it is a precious name that is on the verge of extinction."

Wu Tianyuan picked up the pot, communicated quickly, remembering the clues and feelings carefully, these are all treasures!
"The mud has to go through several processes. First, it is drying the mud. The mined purple sand mud is exposed to the open air, and let it be exposed to the sun, wind and rain. Because the newly mined purple sand mud is extremely hard and strong in nature, it must Expose in the open air, let it weather and disintegrate naturally under the sun, wind and rain, the longer the weathering time, the better."

"Then it is obsolete. The mined purple sand mud ore is dried, screened, crushed, mud powder is collected, sieved, stirred with water, vacuum-formed, and the purple sand mud is refined into mature mud and placed in a damp place. The place needs to maintain a certain temperature and humidity, and the wet mud will become sapropel after aging. Let the water evenly distribute, make the mud rot, and decompose the organic matter to produce colloid. This method is to cultivate the soil.”

"The benefits of cultivating soil can improve plasticity and reduce cracking during the molding process and drying in the shade. After being fired into ware, the skin crystallizes and moistens. It is used for a long time, gradually revealing its edge, and the growth changes greatly."

Xu Sihai picked up another pot and said, "This is Duanni, a rare mud in the early days, which was refined from the original green mud in Benshan. The mud contains relatively large particles and the loose body is obviously double-pore structure, and the air convection Smooth; early mud mix and early kiln temperature rise is relatively low, in general satin mud products will "vomit black"."

"In recent years, the kiln used is a high-temperature kiln. The temperature of the satin clay pot fired can be easily raised, and the real crystallization is relatively high, and it is rarely blackened. It feels sweet and tender, firm and moist, and is almost field yellow. It is well blended and has good air permeability; the tea soup is smooth and comfortable, and the operation skills of tea brewing are not high, so it is very suitable for beginners. It is suitable for brewing Pu'er tea series, Tieguanyin and semi-fermented teas."

"This is Dahongpao, interlayer tender mud mined by Yixing in the small coal kiln mining area at the intersection of Rentu Village and Hongwei Village. It contains iron oxide. Natural iron red powder is added during the mud refining process to enhance the red color. After kiln firing, it will become Bright red, fine and fine mud, high density, high crystallization, soft and delicious tea.”

"This mud is eye-catching red, with elegant temperament, which makes the viewer full of auspiciousness and good luck. It is the ultimate vermilion mud that is on the verge of extinction! Dahongpao mud has low tension, and the shrinkage ratio is almost three times that of purple clay. It is not easy to control the properties of the mud when making it, and it was used in ancient times to add color to the red mud, and it is one of the most mysterious and top-quality vermilion mud in the legend."

"When firing, it is easy to wrinkle, crack, collapse, deform, and when the kiln temperature is light, it turns yellow and is easy to restore, and if it is heavy, it deforms and blisters. The yield is less than [-]%. After firing, the texture is dense, compact and meticulous, and it is solid and heavy. , Ruddy and gorgeous, the best in mud, incomparable. The color changes greatly after soaking in hot water, showing red and purple, and it is easy to show the beauty of "encapsulation" in a pot."

Wu Tianyuan quickly took it over and studied it. This is the top-quality mineral slime he was looking for, and the purple sand pot of Tianyuantang should also be high-end.

"Clear cement is raw purple sand, hematite and mica are common mud materials in the early stage, the mud properties are easy to grasp, and the stability is high. It is a kind of superior mud material in purple sand mud. The mud color is mellow and elegant, and the literati It has a strong atmosphere, and works of all sizes can show the elegance of purple sand; it is easy to resonate with users, and it is one of the most popular clay materials used by potters in the early Ming Dynasty."

Xu Sihai warned: "This is also the main mud used by many unscrupulous merchants in the market for antiques. They use clear cement to imitate the old pots of Ming and Qing Dynasties. After some special techniques, they are quickly coated with paste, pretending to be master pots to deceive people."

Wu Tianyuan also looked at it, and kept in mind that this kind of mud is also valuable, and Tianyuantang can use it for antiques in the future.

"Tibetan blue plaster is also a mud that was widely circulated in the late Ming and early Qing Dynasties. In recent years, the amount of mining has been small, so the finished product is very rare. It has a deep purple-gray tone, because it is full of particles, and has a special touch. Players like to call it "shark skin." It is extremely rare premium grade mud ore.”

"After firing, the double pore structure is obvious, the air convection is smooth, simple and elegant, full of old flavor, and has a unique charm of the purple sand raw material of the Ming Dynasty. The sand feels heavy but not shaved, and the color is like purple or gray. It is heavy, solid and uncompromising, like a tough guy. Suitable for brewing black tea, green tea, oolong tea, etc."

Xu Sihai finally picked up a pot, and couldn't put it down: "I personally like Jiangpo Ni the most. The finished product is full of old flavors, and the orange-red yellowish-yellow appearance makes people look at it and feel nostalgic for the past. It is even more old-fashioned, almost the same as Ming and Qing Jiani!"

"The tea soup is mild and mellow, with a strong aftertaste. If it is used with the previous generation's heirloom as the variety, it will not only have obvious patina, but also have the same flavor and texture as the ancient masterpieces. I love the charm of old teapots." Collectors love it!"

After listening to the introduction of Xu Sihai, a great expert, Wu Tianyuan's trip was worthwhile. He wrote down several clues about the top mud, and the next step was to go to Yixing to search for mines.

Zisha mud is also a rare resource now, and many factories have already started stockpiling materials, and it was hyped for a while a few years ago.Fortunately, the government came forward to clarify the rumors, and the hype was quelled.

"Brother, it's been difficult to do business recently. I invite you this time because I hope to sell some of my favorite things. You have a museum and are a real top collector. I can rest assured that these treasures will be handed over to you!"

Xu Sihai was very helpless, he had no choice but to be implicated by the Dongsheng Club, and he lost a lot.The only thing that can be eaten now is Tianyuanhui, which is Ma Tengfei and Wu Tianyuan in front of him.

"No problem, brother, as long as you want to make a move, brother Ma and I will follow, and we will divide when we go back!"

In the end, Wu Tianyuan bought 280 pots from Xu Sihai at one time, including [-] master pots. Now he has enough funds.Buy it first, and choose slowly when you go back.

"Uncle Liu, I have collected a lot of purple clay pots, and I will send you the photos, if you like them, I will send them to you."

Wu Tianyuan hung up the phone, and the best thing must be given to Liu Huasheng. He is a tea ceremony master, and this is his future weapon and ammunition.

"Brother Ma, you can choose the rest, I don't care, just make an exhibition hall for display."

"Then I'm not polite!" Ma Tengfei was also not polite, he chose more than a dozen and said, "Don't divide the rest, they will all go to the museum, just to set up an exhibition hall, and my collection will eventually go in, sooner or later !"

Wu Tianyuan doesn't care, there are still three museums vacant in the Tianyuan Art Center, and the eight members of the Tianyuan Club have reserved a museum for themselves to store and display collections in the future.It's really a matter of time, just keep a few hands in your hand to play, no more is useless, it's better to let the public appreciate it.
