Cold porcelain

Because most of the ingredients are biodegradable, lemon juice or sodium benzoate are sometimes used to prevent the growth of bacteria and fungi.

It is most often used for at-home crafting and sculpting due to it drying from air exposure rather than heat curing.

[1] Cold porcelain tends to behave like plasticine thanks to its composition, consistency, softness, and malleability.

Due to its easily degradable nature, preserving cold porcelain is important, and can be done through storage in airtight containers.

Mixing with excess water will result in an overly sticky medium, and can be combatted with cornstarch or petroleum jelly.
