DuanNi

Duan mud, also called group mud, is a kind of syngenetic mineral soil of Benshan green mud and purple mud. Benshan green mud and purple mud are the raw ore of purple sand. Origin: Huanglongshan, the raw ore greenish-gray, is the fat in the interlayer of purple sand mud, it is beige after firing. Kiln temperature: 1180 degrees. Shrinkage ratio: about 12%. The meaning of symbiosis is natural formation, and the nature of the two mud is the same, the section mud raw ore is very rare and expensive, and now Yixing pot maker began to use Benshan green mud and purple mud to manually mix, forming unnatural section mud. The quality of the mud is characterized by the purple mud particles are not very obvious. In the green mud of the mountain, it seems to only play the role of changing its color. There are layers, like jade. Part of the mud can not be burned Benshan green, Benshan green mud is very delicate a pure yellow color. Segment mud is used in the pottery industry. The purple sand ware fired by the section mud will also change based on the section mud, not only in terms of color, but also in the effect of sand adjustment.

· Features:

[Kiln temperature] : about 1175~1180 degrees.

[Shrinkage ratio] : about 12%.

[Clay] : sweet, tender and dense, firm and warm, with a near-tian yellow color, for Jiangsu Yixing Zhaozhuangshan system of Zhuangshan mud ore ~ yellow, after picking and refining, because the iron content is only about 6%, after pottery was "Jintian yellow".

[Features] : many players mistakenly believe that the satin mud will "spit black", the cause of the misunderstanding, is that the kiln is low temperature kiln, and the satin mud is high temperature mud (generally burning temperature of about 1175~1180 degrees Celsius), so every kiln is insufficient, and the finished product is restored to the phenomenon of raw mineral color after water (players called "spit black"); This is caused by insufficient kiln temperature, rather than the defect of mud, I hope the player does not reverse the cause and effect is.

· Distribution:

The section mud is distributed in the syngenetic ore from Zhaozhuangshan red mud ore to yellow stone in Yixing, Jiangsu Province.

· Use:

[tea characteristics] : satin mud suitable for brewing tea is more broad, in general, the permeability is good; The tea soup is smooth and comfortable, and the operation of tea making skills is not high, and it is suitable for novice use.
