When making a Jianshui purple pottery pot, each step is closely linked, and the order is particularly particular. It depends on the specific conditions of each process.
Generally, after rough trimming, engraving and filling decoration are carried out. After filling, mud will be spread, mud pressed and scraped. Until the last step to scrape off the extra color mud, the engraving and filling of the picture will still appear fuzzy and rough.
At this time, we need to finish the blank, one is to further repair the mold to the most ideal state, the other is to make the engraving screen fully displayed through the fine trimming blank.
Because in the process of finishing, it is necessary to put the pot blank on the billet drawing machine and rotate it at a constant speed. Once the spout and handle are first bonded, such finishing can not be completed.
Another reason is that it needs to consider the coordination with the body of the spout and handle, so as to produce the best appearance. Therefore, it is required that the body of the pot should be refined to the best shape, which can not be repaired again. In this way, according to the size of the pot body, the height, the thickness, and the handle of the spout pot can be bonded to achieve the best.
Because the external finishing can not be carried out after bonding, only careful care is needed after bonding, and then the drying stage can be entered.
Sometimes after bonding, it will be found that the pot is too thick, and then it will be thinned by internal trimming. However, it is difficult to locate and fix the center point of the teapot with the spout and handle when it is rotated on the billet drawing car plate. This kind of teapot can only be used when it has to be forced. Therefore, in the finishing stage after the completion of engraving, the main shape and thickness of a pot have been determined.
