Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem that the scattering of the dust of an investment compound during a dental casting work can not be prevented, especially the problem that a technician may suck the scattered dust to cause the trouble of pneumoconiosis, and the problem that it is impossible to quickly carry out a kneading work, because raw materials must slowly be stirred to avoid the scattering of the dust in the kneading work. SOLUTION: A two composition-mixing type phosphate-based investment compound for the dental casting comprises (a) an aqueous composition comprising a water-soluble phosphate, a fire refractory material, and water and (b) an organic composition comprising a basic compound and an organic compound.
