みでは前記欠点を除くために十分ではなかった。Here, in an attempt to improve the efficiency of casting work,
If the fluidity of the slurry of the base material is increased, the water content of this slurry will increase, and conversely, the burden on the water absorption f of the plaster mold will increase, which is not appropriate. Additionally, there is a method in which the outside of the plaster mold is evacuated to increase the water absorbency of the plaster mold, but this method alone was not sufficient to eliminate the above-mentioned drawbacks.
