The use of petroleum jelly or another release agent is recommended, as the print is porous and the cement may adhere to the mold

The mold test was conducted using a mixture of two parts gypsum to one part cement

Demolding occurred after 15 to 20 minutes

The piece was submerged in water for one day to allow the cement to set

If removing the cement piece from the mold proves difficult, submerge it in water for at least one hour before demolding
