The molded body can be cured by treating the gas-curable resin with a curable gas in the container, and sufficient cured shape can be imparted to the cured molded body. In addition, since the compact obtained by molding the kneaded clay in the mold does not have sufficient shape-retaining property, a supplementary plate is set on the bottom of the mold, and the compact is set on this supplementary plate. In this state, it is preferable to take out from the mold and load it into the gas treatment pressurized container. The gas capable of curing the gas-curable resin is preferably used in an amount equivalent to 30 to 70% (weight ratio) of the added amount of the gas-curable resin.

を表１に併記する。The present invention will be further described with reference to the following examples. Example 1 A kneaded material was prepared at the compounding ratio shown in Table 1, and a molded body having a predetermined bulk specific gravity was obtained in a mold having a supplementary plate at the bottom. After removal from the mold, it was then loaded into a gas treatment pressurized container. Next, after the pressure in the container was reduced to 400 mmHg or more, carbon dioxide gas was supplied at a rate shown in Table 1. In addition, a safety valve is installed in the container, and in this embodiment, the supply pressure of carbon dioxide gas is 3 kg.
/ Cm 3 and the safety valve is 2.9 kg / cm 3. Therefore, the safety valve is -0.1 kg with respect to the carbon dioxide gas supply pressure.
