A friend asked me a few days ago if kaolin is only available in Jingdezhen
I said 2 words simply and clearly No
China was the first country in the world to discover and use kaolin in the Shang Dynasty Neolithic period carved white pottery is made of kaolin clay because kaolin clay makes Jingdezhen porcelain as white as jade thin as paper as bright as a mirror
Kaolin is a non-metallic mineral Made of Kaolinite clay and clay rock Porcelain made of porcelain due to the binary formula of the Yuan Dynasty began to use the macang soil produced in Macang Mountain near Jingdezhen as the raw material for porcelain making Until the Ming Dynasty Macang soil was completely exhausted during the Ming Dynasty Jingdezhen porcelain makers began to use kaolin soil located in Gaoling Village, Jingdezhen
Pure kaolin is white and delicate, soft soil with good plasticity and fire resistance
Since then, kaolin has begun to replace porcelain stone as the main raw material for Jingdezhen porcelain Kaolin is an associated group of ore groups mainly containing kaolinite quartz feldspar and other uses are very extensive, not limited to the porcelain industry
Kaolin clay has many more names that may be more familiar to everyone, and one name that is actually a silicate mineral containing aluminum is mainly white soft mud, fine particles like flour Different caves and different rock layers of kaolin texture composition can directly affect the change of ceramics in the kiln
The kaolin on the Kaolin Mountains was mined in the early Qing Dynasty and weakened during the Guangxu years because of its best quality, white and delicate, and it also achieved the glory of the Ming and Qing imperial kilns for hundreds of years
Today, Gaoling Mountain has become a tourist area Most of the mines left over from the Ming and Qing dynasties have collapsed and closed
The original kaolin of Jingdezhen was actually mined almost as much as it was in the 1960s and 1970s
At that time, 7501 porcelain was also kaolin that was urgently transferred from Fuzhou
In fact, there are kaolin mines in the area around Jingdezhen in Fujian, Guangxi, including many places abroad
However, since the beginning of the binary formula porcelain making, the use of Jingdezhen kaolin and the high quality have created the glory of Jingdezhen porcelain
A lot of players who don't know about it will think of kaolin mythology as a kind of porcelain ingredient
There's only a little bit of that in the mud recipe, which we call bone in jargon, sorghum
In fact, now as long as the slightly better porcelain clay raw materials will be mixed with kaolin, it is only a matter of how much is used The more kaolin in the tire mud, the more white and delicate the whole porcelain tire will be
However, the higher the kaolin content, the harder the fetal bone, the more difficult it is to combine with the glaze, so this is why there is a problem of shrinking glaze pinholes
Finally, I would like to explain to you again that we only choose to meet our standard requirements to ensure that the quality is really aesthetic to represent the oriental elegant kiln cooperation, so please don't come up and ask me how so-and-so kiln is
Some I have not heard of nor dealt with I am also a porcelain seller, no matter what position I take to evaluate other kilns, there is a kiln we cooperate with before you start to have a little basic understanding of it, in addition, I am not a good sleep you say that you send me messages in the middle of the night to be woken up I am in the spirit of the opportunity to have business to come to the door I am back or not back? Confused and risking the risk of breaking the porcelain Sent a photo Finally because the price is not suitable, it is not very embarrassing
