Many pot friends think that there is no need to care very much about whether the teapot is handmade. Pure manual is not necessarily good, and semi-manual is not necessarily bad. The main thing is that the mud is pure and correct, and don't mix it with additives that have an impact on the body. Because of the price disparity, whether it is handmade has attracted much attention. As far as pots are concerned, there is an essential difference whether they are handmade or not. A basin friend summed it up very reasonably. He pointed out that hand-made pots are cut, scraped and repaired on the outer wall after repeatedly patting mud slices, and each process takes a lot of effort. However, the time for making molds is not jumping. After basic molding, time is spent on the inner wall to match the mud with the tool. When making pots by hand, a mud layer is formed on the outer surface of the blank, and the inner layer is loose, and the sand particles in the middle gather to form mud and sand to strengthen bones, so that the unique permeability of purple sand is well preserved. After firing, the texture shrinks differently, the muddy sand layer is uneven, and the appearance is rough, which makes the surface of the pot show a warm texture and bright luster. Because of the loose mineral structure and the accumulation of sand particles, the inner wall of the pot shows the essential function of internal seepage and external suction, showing the unique performance of purple sand. However, the balance and identity of the mud made by the mold are greatly destroyed, and the inner and outer walls lack a sense of three-dimensional structure. After firing, the surface loses its texture effect, and the absorption rate of the pot wall drops to over 60%, leaving almost no unique performance of purple sand. The most outstanding performance is: after a long time of use, it often appears gloomy and rigid. In the identification, there is a trick to identify the mold pot. Generally, there is a thin trace from the spout to the handle in the middle of the pot, which can be found by careful observation.

Now many sellers wax pots in pursuit of luster. No expert pot friend will buy a wax pot. In fact, a good clay pot does not need to be waxed, and a waxed pot is definitely not a good pot and has no collection value. How to tell whether the pan is waxed? First, it feels particularly bright. Second, there is a strange feeling of touching wax. Third, the water will quickly gather into water droplets and roll down. Fourth, it may smell strange.
