Fujian Jiandan Tea Set

Jianyao black glaze is a kind of crystallization glaze, which belongs to the lime glaze with high iron content, so it has the basic conditions for firing black glaze. At the same time, the lime glaze has strong viscosity, and its biggest feature is that it is easy to flow at high temperature, so the bottom of the outer wall often has the phenomenon of hanging glaze, and the object mouth is thin along the glaze layer, is brown red, and some are similar to awn mouth. The basic characteristics of Jianyao black porcelain are as follows: the cross-section color is black, gray black, black brown, which is caused by high iron content; Fetal bone thick and hard, knock metal sound, commonly known as "iron tire", feel thick; It contains more sand, so the fetal quality is rough, and the feel of the exposed fetus is also thicker. From the analysis of firing technology, the black porcelain of Jian kiln is fired at high temperature, if the embryo soil is too fine, the ware is easy to deform. It is precisely because of the heavy body of Jian Zhan in Jian kiln black porcelain, there are small pores in the tire, which is conducive to the heat preservation of tea soup and suitable for the needs of tea fighting.
