A. Begin with the clay material, correctly mastering the proper consistency of the clay, and prepare good clay coils and slabs. B. The body cylinder must be beaten well. If there are wrinkles when beating the clay or forming the body cylinder, wrinkles will appear after firing. If the hollow body cylinder is formed by hand, it must be consolidated. Expanding the body cylinder is to strengthen its resistance and make the cylinder round and even. The timing for consolidating the body cylinder must be well controlled—when the resistance limit and hand feel are just right. If the resistance limit is exceeded, it will require much greater effort to consolidate again. Expanding the body cylinder has another function: according to general principles, after the bottom is gathered and closed, the diameter of the belly will necessarily be larger than the circumference. To achieve the correct form, this requires the method of beating first (Figure 1, Figure 2). > Figure 1 Figure 2 Figure 3 C. When rolling out slabs, attention must be paid to proper consistency. D. Tools must be used properly, and moreover, tools should be considered beforehand and necessary auxiliary tools prepared in advance. E. Attention must be paid to processing aspects. For example, to ensure the mouth and lid fit properly, one should use a mouth-opening gauge to measure the outer root of the already formed mouth rim. If it is correct, then the mouth and lid will certainly fit well. For straight large mouths, a separate gauge for measuring the mouth rim should be prepared to ensure the quality of the mouth and lid fit. ## Detailed Operations A. Key points for opening the mouth: (1) The mouth-opening gauge must be good. The mouth rim area should not be scraped; only the sharp edge needs to be beveled. (2) The lower edge of the mouth cannot be slanted; it must be straight. If it is uneven, simply use a pointed knife to level it. (3) To remove the lower edge corner, a specialized scraping tool should be made to scrape evenly and uniformly. (4) To make the inner mouth even and uniform, use a needle tool to make a scraping tool and scrape evenly (Figure 3). B. For the interior walls and bottom of the teapot, the marks from the small paddle should appear in a radial pattern. The junction between the bottom and walls must be pushed smooth and润. *Shanshuicun*
