The water absorption of the purple clay pot is not good, is there a problem with the mud?
Many pot lovers like to use boiling water to pour the body of the pot, judging the quality of the material from the speed of water absorption. Why? Because it is said that the surface of the chemical pot is smooth and waxed, it does not absorb water, so some pot friends believe that the faster the pot absorbs water, the better the material......
The water absorption of the purple clay pot
The speed of water absorption of the purple sand pot is related to the crystallinity of the pot firing, the shape of the purple sand pot, the number of meshes of the purple sand pot, etc., and the water absorption of the new pot is generally stronger than that of the used pot.
Because the purple clay pot is not a sponge, it is not normal if you pour as much water as you pour and absorb as much water, and if the water absorption is so serious, won't the pot become heavier and heavier? Therefore, this view itself is wrong.
Why is the purple clay pot absorbent?
What we call "water absorption" and "hanging water" is actually because of the double air permeability of purple sand mud, and the water is gone after a pot of water is poured, more because the experiments you see are generally filled with hot water and then drenched, and part of the heat inside will be released through the pores. Therefore, after pouring water on the pot, the water will evaporate quickly.
What is water absorption related to?
A pot friend asked, after his pot was brought back, it was not hung with water, and then he washed and wiped it in various ways, and after a while, he could hang water again, and asked me if there was wax on the pot?
First, the water temperature determines the speed of evaporation, and the temperature of the water and the surface area of the pot all affect the water content.
The second type: some will wax on the surface, which will affect the breathability of purple sand.
The third kind: it is related to the process of making the needle, a pot on the needle and five times on the needle, then its degree of hanging water is not the same.
Fourth: It is also related to the mud, the mesh of the mud of the pot itself (the higher the mesh, the more delicate the sand) is high, the fetal soil of the pot is relatively dense, and the increase of the double pore structure makes the water absorption performance of the pot greatly improved, of course, it will dry quickly. Like the high shrinkage ratio of vermilion mud, it has a high degree of porcelain after firing, and the surface is very smooth, so it is not very water-hanging.
Fifth: It has to do with the shape of the pot. For example, Shih Tzu pots, dragon egg pots, this kind of pot basically does not have the opportunity of water accumulation on the pot, the whole body is slippery, how can there be a reason for the water to dry unhappily! And such pots as antique, flat-lid lotus seeds, and virtual flats are excessively very gentle, and there is a chance of water accumulation on the lid of the pot, and the water in the body of the pot is also slow, and the relative drying is slow.
Sixth: This is also related to whether you have raised, a pot may be you often drenched in the early stage of use, it is quite hanging water, and then it will not hang water, this is because in the process of raising, the surface of the pot is more moist after the pulp, and it will also lead to what everyone calls "how to raise and raise without hanging water".
summary
There is no direct connection between the speed of the pot drying and the mud, and there are many variables, at most you can see whether the water absorption is good or not. Therefore, the speed of water absorption of the purple clay pot cannot be used to measure or judge the quality of the mud of the pot itself. If you blindly pursue the water absorption of the pot, you will not only miss a lot of good mud, but also easily walk into some unnecessary misunderstandings.
