Put the starch in a large saucepan. Add the cold water gradually, stirring until there are no lumps. Continue to stir while adding the boiling water, and cook over medium heat until clear, stirring constantly. When mix thickens, add the soap flakes and talcum powder. Remove from heat and beat with an egg beater until smooth. Mixture should be thick. Store in a plastic container in refrigerator or use while still warm.
