Mold preparation

The mold box is filled with high mesh class silica sand, mixed with water glass and methanol liquid, and stirred to homogeneity. In the next process, silica sand is poured into a box to create a hole trace pattern following the planned specimen shape and dried with CO2 gas. However, before the silica sand is poured into the mold, the chill plate, Y-Block pattern, and thermocouple cable were first attached to the surface and positioned in the mold (Fig. 2a and 2b).
