Typical casting slip has a specific gravity of 1.8, that means it is a lot heavier than water. The deeper a mold the more outward pressure the slurry will exert. There is thus good reason to be certain that the mold halves are securely held together. If not, this will happen!

Pour Spout
Plaster molds intended for slip casting have a spare at the top to act as a reservoir. This enables overfilling the mold to accommodate the dropping slurry level. 3D-printed spouts make a spare unnecessary. |

Slip Casting
A method of forming ceramics. A deflocculated (low water content) slurry is poured into absorbent plaster molds. As it sits in the mold, usually 10+ minutes, a layer builds against the mold walls. When thick enough the mold is drained. |
