Figure 2 shows a combination of the convex plaster mold, the clay, and the concave rubber plate, and the shaded area is the clay. 3 will be tatami.
Figure 3 shows the convex plaster and 4 shows the widened chasen part. Figure 4 shows the clay placed on top of the convex mold, the shaded area is the clay, and 5 is the clay layered by the spread of the chasen. Figure 5 shows a combination of convex molds, mulched soil, concave molds, and rubber plates, and the diagonal lines are the mulched soil.
6 shows the gap that was created when the clay was pressed down and spread out on the part where the waist of a bowl, etc. widened.

Claims

[Scope of Claim for Utility Model Registration] The process of molding ceramics using a mold made of plaster is called mold raising. There are two types of molds: convex and concave pressing molds that use clay, and casting molds that use slurry. The proposed method is to form the mixed clay using two molds: a convex mold and a concave mold. At that time, the bottom part of the concave shape (the part with the elevated part in the case of a tea bowl) is made hollow. The scope of the claim is (1) a concave plaster mold with a hollow bottom; Fill the hollow with clay, press-fit a rubber plate, gypsum board, etc. corresponding to the depression in the platform into the bottom part filled with clay, remove the protruding clay, and create a platform, i.e. (2) Disk for that purpose. shaped rubber plates, gypsum plates, etc.
