PURPOSE:To obtain a porcelain kneading agent, having a specific refractive index, consisting of an organic solvent, such as a phthalic acid ester based liquid plasticizer, without changing color tone of a porcelain paste during kneading and building up after firing and capable of preserving the color tone even thereafter and useful for repairing a dental crown. CONSTITUTION:A porcelain kneading agent, consisting of an organic solvent having a refractive index almost equal to that of crystal grains of porcelain paste for repairing a dental crown, preferably phthalic acid ester based liquid plasticizer (particularly preferably one or two or more selected from diethyl phthalate, dibutyl phthalate and dimethyl phthalate) and useful for repairing the dental crown. When this kneading agent is blended with a porcelain paste for repairing the dental crown, color tone of the porcelain will not change before and after firing since the refractive indexes thereof are extremely approximate.
