Cold porcelain is a glue mixture that hardens into a durable, smooth compound. It can be used for many different decorative features, from flowers to flat sheets for painting. Before it dries, cold porcelain is slightly flexible. It can be flattened into a sheet and cut, then rolled into designs and decorated. The recipe for cold porcelain is easy to make at home, and a valuable tool for anyone who undertakes hand decorating. It is especially useful in making flowers for decorating crafts and cakes.
Combine glue, cornstarch, water, cold cream and glycerine in a pot. Add food colouring if desired, though the flowers will look more realistic if they're decorated after they're formed.
Stir ingredients over low heat for about 10 minutes, or until the mixture starts to develop a doughlike consistency.
Remove the pot from the heat and allow the dough to cool.
Remove the dough from the pot and use your hands to knead it. Knead until the dough is smooth and claylike.
Roll the dough out using a rolling pin and cut into strips. Model these strips into flowers as you would with modelling clay.
Paint the flowers with a waterproof sealer. Allow 24 hours for the cold porcelain to dry before adding any other colour or decorations.
For a realistic look, dust white cold porcelain flowers with powdered food colouring, then hold them in a column of steam.
Don't use good cookware for making cold porcelain. Cold porcelain will dissolve in water unless it's been properly sealed.
