Identify the advantages and disadvantages of purple clay mud

The raw ore and mud of the teapot is three kinds of purple clay, green mud and red mud, commonly known as "rich and expensive soil." Clay pots are made from clay and clay pots are divided into three types: purple clay, green mud and red mud. The mud that can be used to make teapots is generally buried deep under the rock layer of the teapot and distributed between the clay mud layers. The thickness of the mud layer varies from tens of centimeters to one meter.

The difference between true purple sand and chemical mud is as follows: Identifies the original ore of purple sand, refined light, restrained, warm jade, calm, old-fashioned. The use of good materials can be seen in less than ten days and a half months. The low-grade chemical mud pots, no matter how they were raised, did not change much, and they were still dry. Although it is also possible to make so-called green bean sand effect (not all clays have the effect of green bean sand), but because the surface of the glass phase (also known as the addition of shavings water is also known as quartz water) is too heavy, the tea can not eat The oil that is used to play can't penetrate, so this type of pot cannot be raised. Now that the Zisha Research Institute has paid attention to this topic, it has produced chemical mud without glassy phase on the surface. This kind of mud is used as a high-end imitation famous pot, and it can deceive people very much. It is not familiar with the original slime and chemical mud. , extremely easily taken in.

The difference between true purple sand and chemical mud II: The colors of mud color mud ore mud will not be too bright. First, because the early purple sand was a superficial layer, there was a certain amount of primitive weathering. Second, since the purple sand mine is excavated from the ground, it is necessary to place the open air space in the sun and rain for a year and a half. After the natural loose material becomes small particles, it is ground into a powder, and finally it can be used by hammering and stale. The weathering and aging of the metal materials in the raw ore mud will oxidize, and the mud will be dark, heavy and old, and will not have a fresh and beautiful feeling. Some of the mud will be aged and stored for decades or even more than a hundred years. Therefore, there will be a small amount of old mud left in the Qing Dynasty, but it is already precious and scarce. The chemical mud is prepared from kaolin plus quartz sand, shavings water, and chromic metal oxides. It is now used, and metal oxides are often added excessively. Therefore, it is unsurprising that the mud pots are bright and muddy. If you use this kind of dyed tea, you can imagine the effects on your body. Zisha pots of raw ore and mud are all darker and darker, especially the ones that have been used are particularly noticeable. There is an old-fashioned feeling that is full of years. This is what we talk about. The chemical pot will definitely not achieve this effect.

The difference between true purple sand and chemical mud III: Discerning the process Due to the modern production process specification, the efficiency is extremely high. The pots made by Zhou Zhengzheng are well-behaved, which makes many beginners like it very much. The pots made by hand do not have the same mold. They rely on the artist's ingenuity and experience, and they are well-prepared for their own preferences. Therefore, the unified shape system and the uniform specifications of the pot will be in the shape of the body, the diameter of the mouth of the spout, and the installation position of the spout and the spout. The thickness will vary, and there will be no pot with the same appearance and specifications. In addition, the original ore is very rare and very valuable. It is impossible, and there are not many large-scale mechanized and mold-making batch production of mud. Therefore, distinguishing the traditional craftsmanship is still a modern craft, which is also an aspect of judging whether the mud is a tunnel.

Teapot is used for making tea with tea. For the performance of the teapot, “color, flavor, and concentration” has long been inconclusive. In addition, scientific institutions also conducted detailed tests on the sand pots and ceramics on the “smoothing of the moon and the moon”. It is indeed confirmed that the sand pots are superior to ceramics. This conclusion is based on the raw materials of the purple sand. unique. Zisha pot has strong practicability because it has a relatively high porosity, which makes it have the advantage of good air permeability.
