Cold porcelain is a crafting material most commonly made from cornstarch and white glue, not from porcelain as its name would suggest. The material can also include small amounts of oils and glycerol. Because most of the constituents 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. The material can also be dissolved by heat or water.
