Cold porcelain offers do-it-yourselfers an alternative to polymer clay. Jewelry-makers on a budget will love cold porcelain because the assembled materials cost less than $15 dollars. Many crafters may already have the necessary items, meaning the process costs nothing at all. Chalk is a key ingredient in cold porcelain because it adds color and a little more stability. This is especially important when crafting porcelain flowers.
Mix ¾ cup of white glue, ½ cup of water and 1 teaspoon each of cold cream and glycerin in a large saucepan. Stir constantly over medium heat until the ingredients form a thick, white paste. Add a cup of cornstarch and stir until the mixture attains the consistency of mashed potatoes and pulls away from the sides of the pan.
Pull the cold porcelain out of the pan and set it on a piece of wax paper. Divide it into the different parts for your flowers -- leaves, petals and centers. Choose a chalk powder color for each. If making more than one kind of flower, divide your petal porcelain again to account for petal colors.
Sprinkle about a teaspoon of chalk powder on each lump of cold porcelain. Knead and roll the porcelain until the chalk is totally incorporated. Less kneading results in marbled color, more kneading makes the color smooth and uniform. Either one works well for molding.
Examine your mold. Pull pieces from the appropriate colors of porcelain and place a small piece of porcelain in the center of the flower, place the petal-colored porcelain in the petal spaces. Do the same with the stems. Make sure you fill the mold.
Press the porcelain firmly but gently into the mold, then turn it over on a clean sheet of wax paper. Bend the sides of the mold up so the flower pops out. Allow your flowers to dry overnight.
You may also assemble your flowers by rolling out individual pieces and gently pressing them together. You can also glue the pieces together after they dry.
