The Sensory Characteristics of the Ceramic Fetal Containing Ma Cang Clay
There are some common features in the typical cymbidium.
The base of Yuan Qing Hua is exposed to the fetus. It has a greasy feeling, such as the baby’s buttocks, which is very comfortable.This silky comfort is often accompanied by the surprise of puncturing the visual impression.Because of the rough and soft visual impression of the base of many Yuan objects, once reached out for close contact with them,that sortThe creamy feeling that is completely different from the visual impression, bring you is a kind of concomitant surprise.

2-glutinous soft feeling
Different from the greasy feeling, the glutinous soft feeling of the Yuan-Qing-hua tread soil is a good synergy between visual and tactile feeling.that sortIt is denser than clay, more glutinous than stone, harder than cork, less dense and less loose, powder-like and non-dry, rough and greasy sensory impression, much like the middle way of Chinese culture.
3-There’s a thin crack inside
If you use a magnifying glass to extend your vision to the inner microstructure of the original blue-and-white porcelain tire, you will find that the cross-section of the ceramic tire, often small cracks, a bit like the hand to squash the cork after squashing, followed by the cork material of the gap also squashed feel.
After a large number of pictures and objects to observe, in the capture of the addition of ma cang earth brought about by the typical yuanhua porcelain tyre characteristics, I was surprised to find that the typical yuanhua porcelain between different objects, the sensory impression can be so different.

understanding of mackang soil
Ma Cang soil was first found in the literature, which was in the early years of the Ming Dynasty.
Makang soil is a kind of high-quality kaolin, produced in Fuliang County Xinzhengdu Ma Cangshan so named.
Physical characteristics of kaolin: pure kaolin has high whiteness, soft quality, easy to be suspended in water, good plasticity and high cohesion, good refractory and other physical and chemical properties.
Ceramic stone is formed by long-term heating fluid and weathering of granite, mainly containing quartz and sericite.Before Yuan Dynasty, porcelain stone was the main raw material for making porcelain in southern kiln mouth.
Ma Cang soil is a kind of kaolin, except the unique place of origin in Ma Cangshan, there is no data to highlight its essential difference with other kaolin.And kaolin mine is still a large number of, binary formula from the Yuan Dynasty, Jingdezhen has been its continuation to the Ming, Qing, until today.
Therefore, it is unlikely that there will be unique features due to the addition of Ma Cang earth.
But, from the sense impression of porcelain tyre, typical Yuan Qing Hua really has certain characteristic: Smooth feeling, waxy soft feeling, not too dense and not too loose, the tread soil section has obvious gap, and so on.
. ..the flint red of the Yuan blue-and-white porcelain.
During the Yuan Dynasty, Yakura soil began to be used in the production of blue-and-white porcelain.Makang native to a place near Jingdezhen called Ma Cangshan, is a kind of high-quality kaolin containing more iron molecular structure.Flame is produced in some places because of the iron content and the main tire-making material, porcelain stone, combined with the formed-tire soil material.For example, the bottom foot surface, foot-foot glaze joint, the edge of the floating glaze droplet (the mouth along the inner surface, the inner surface will have this kind of glaze droplet).
In addition to producing flint infrared in the process of firing, some unearthed objects will also be in the buried soil in the moist environment, or in the humid closed environment of the original flint red features enhanced.
This flint red color is a combination of orange, brown and yellow, with a semi-metallic sheen on the surface.A narrow line of orange-red-brown yellow that oozes at the edge of a glaze drop or at the junction of a foot-foot glaze.Although it is a kind of orange, brown and yellow, but the color is integrated, and there is no yellow exposure, that is, sometimes partial orange red, sometimes slightly brown, will not bias yellow to come (people fake flint red edge will often turn dark yellow to).The surface of the foot exudes a little orange, brown and yellow, often accompanied by the presence of some black spots symbiosis.When there is a large amount of flint red, the base is covered with a large area of pigment, that is, it is covered with flint red.
The flint red phenomenon is a very important feature.Although some blue-and-white porcelain bodies do not necessarily have flint red, but generally speaking, people prefer flint red objects.Because there is flint red, can more fully show the Yuan Dynasty blue-and-white porcelain style.
The essential difference between true flint red and false flint red is summed up in two words.
Unfortunately, the mackang soil was exhausted in the ming-wan-li period, and ancient porcelain and stone materials disappeared as early as the republic of china.

Makang soil is Kaolin
Ceramic stone: For stone raw materials, Mohs hardness 4 ~ 7 degrees, must be hammered into powder, and water for no.
Kaolin: For the soil raw materials, do not need to crush, only use the elutriation method to remove the coarse sand can obtain the clean mud.
Kaolin, whose mineral composition is mainly kaolinite (or eluoite), does not soften at below 1700 ℃. Admixture of kaolinite to make tire in porcelain can increase the strength of products at high temperature and reduce the deformation of porcelain ware.
Gao Ling mining in the rear, Ma Cang mining in the front.Makang soil is the predecessor of kaolin.
But in the early days of Wanli, the old land of Ma Cang began to dry up.
Since the mid-Wanli period, the literature has no longer seen the record of mackang soil mining, generation, is” kaolin. “

What is kaolin? What is the difference between mackang soil and kaolin?
Kaolin is a general term for porcelain clay used in ceramic history. It has been used internationally.Before the Ming Dynasty Wanli this kind of porcelain soil from the Jingdezhen near the Ma Cangshan, so called Ma Cang soil.In the years of Jiajing of Ming Dynasty, the clay mining of Ma Cangshan will be finished.The kiln workers in Jingdezhen, not far from Maqangshan, discovered the clay similar to Maqang soil, which can be used to make tire porcelain, which is similar to Maqangtu soil, and began to mine the clay porcelain of Gaoling Mountain in Wanli year.After Qing Dynasty, Kaolin was discovered in Lihuang and Dazhou, and was mined in Qianjia years until the founding of New China.The clay used in Jingdezhen since the 1960s was also found to be mined, unlike the old pit soil.The Gaoling soil is different from each other in different periods.After the Qing Dynasty, kaolin was recognized internationally and became an international general term for porcelain clay.
What are the characteristics of the porcelain made from mugang?
1. Mackang clay porcelain must be crushed, washed, stale, among them the process of floating should be and do steamed bread hair face a truth, stale time is long, too soil can fully expand, so fired porcelain feel moderate, will not be like today’s imitation, very heavy.
2. The temperature of the furnace can be raised by using mugang to form a tire, and the ceramic tire is not easy to deform.
3. The foetal color is white and slightly bluish-gray.
4. There are more stomata in the fetal bones, and most of the pores in the fetal bones are narrow because of manual tugging
5.Fetal bottom grain shape is obvious, not as fine as Ming and Qing porcelain tyres.
