Common misunderstandings in the classification of red mud:
Red pilong: Red pilong is a purple sand mud material, because of the red veins on its surface, the original name is "wild mountain red mud", which belongs to a purple mud, not red mud.
Bordeaux mud: Although the name of the bordeaux mud has a red letter, it does not belong to the red mud, but the bottom groove of the red color is clear, which is the exclusive name of the bottom groove clear of this color.
What's the difference between three kinds of red mud?
Zhaozhuang red mud: the lightest color, heavy pulp feeling, the biggest change before and after soaking.
Huanglongshan unmud: strong sand, low temperature orange, high temperature orange-red, hard to pick up.
Small coal kiln mud: red and gorgeous, clear particles, the reddest hair color, a bubble effect.
First, is the saying of "ten Zhu and nine wrinkles" correct?
Wrong! Could be a trap.
Although the vertical shrinkage of the clay pot is greater than the horizontal shrinkage, it can not be summarized with "no wrinkles", and many of the red clay works handed down are wrinkle-free. Carefully selected mud, grasp the mud, properly refined, red clay pot can not wrinkle.
Some purple clay pot table wrinkles, the cause is "punching", that is, grout pot. The raw ore powder is usually 60 mesh, and the powder used for punching is usually more than 200 mesh (the naked eye can not distinguish more than 200 mesh impurities). At high temperatures, mud flows to fill the gaps between the gravel, forming wrinkles or convex sand.
Second, common misunderstanding: wrinkles do not mean that mud is good!
If the purity of the original slime is high, there is no fault between the gravel, there will be no wrinkles and convex sand phenomenon.
Third, why is the water in the red clay pot not easy to dry?
The density of red mud itself is high, so it is most suitable for brewing light fermented Tieguanyin and other high-flavor tea, forcing incense fast and raising incense high. The water in the red clay pot is not easy to dry, which does not indicate that there is a problem with the mud.
Fourth, what is Dahongpao clay material?
There's no real Dahongpao clay. Dahongpao mud is actually the mud with the best quality and the reddest hair color picked out from the red mud, so there is no real Dahongpao raw ore. The addition of stone yellow red mud, the so-called "Dahongbo" mud, plasticity is greatly increased, the ductility is strengthened, the mud sheet is not easy to break when bending, the burning temperature is about 1040℃, and the shrinkage ratio is about 45-55%. Texture and moisture will be enhanced.
