The so-called texture refers to the feeling of mud on the surface of the pot body. The raw purple sand is clean and restrained, moist as jade, calm in tone and antique. Good mud can be used, and the effect can be seen in less than ten days and a half months. The low-grade chemical pottery pots, no matter how they are raised, have not changed much, and they are still dry. Although it can also produce the so-called mung bean paste effect (not all the mud materials have the effect of mung bean paste), the glass phase on the surface (also called timely water because of the addition of shavings water) is too heavy, so the tea can't be eaten, and the playing oil can't seep in, so the pot can't be raised. Now a purple sand research institute has paid attention to this problem and has produced chemical mud with no glass phase on its surface. This kind of mud is used to make high-grade imitation pots, which is very deceptive. People who don't compare raw ore mud with chemical mud are easily fooled. The specific logo is: 1. Because the sand and mud in raw ore mud shrink unevenly under high temperature firing, some raw ore mud (Zhao mud, Jin Zhu mud, rice bran mud, etc.) will have small longitudinal wrinkles on the pot body. ), especially in corners such as corners of the mouth. Longitudinal wrinkles are evenly distributed, with obvious concentration in some places and sparse in some places. 2. The size of the sand particles in the raw ore mud is different, because the previous mud materials were obtained by natural weathering, and then they were ground by a stone mill through a bamboo screen. So the sand is uneven. The chemical mud is treated by high-speed raymond mill, and the amount of sand grains is very uniform. At first glance, there is a lack of a natural and simple feeling. 3. Raw slime often contains some impurities, that is, some small spots with uneven particles and uneven distribution, especially white spots and gray spots. This is caused by a certain mud mixed with a very small amount of other mud components. The colored sand particles of chemical mud are artificially added, which are distributed all over the body and extremely uniform, making people feel unnatural and uncomfortable.
