1. Is Jianshui purple pottery glazed?
A: except for some works with special needs, the vast majority of Jianshui purple pottery can’t be glazed. In fact, glazing is not listed as the technological process of Jianshui purple pottery.
The last process of Jianshui purple pottery is called glandless polishing, which is to emphasize that Jianshui purple pottery can also be ground to a bright effect like glaze without glaze because of its fine clay.
2. How to distinguish the cut cap from the inlay cover?
A: the two types of covers can be distinguished from each other in appearance.
As the name suggests, cutting the lid is like cutting a part of the pottery body as a cover. It is usually seen in round or oval shapes, such as Xishi, Longdan, Qinquan, etc.
Inlay cover is that the edge of the lid is embedded into the mouth of the pot, which is mainly determined by the shape of the teapot. At the same time, the inlay cover can also achieve better tightness. The common use of inlay cover is in well jar pot and handuo pot.
3. Why is purple pottery cup heavier?
A: I wrote a special article to answer this question. It can be summed up for two reasons
One is to reduce the risk of deformation when firing at high temperature. The firing temperature of Jianshui purple pottery is higher than 1100 ℃, and the body is too thin, so the risk of deformation is great, so the green body will be deliberately made thicker.
The second is to complete the engraving decoration. Jianshui purple pottery is characterized by carving and filling decoration. If the green body is too thin, it is difficult to carve and fill, and it is easy to cut through and crush. Therefore, in order to meet the needs of engraving and filling, the green body will be deliberately made thicker.
Thick green body and high sintering density make the finished product heavier.
