Dental gypsum slurry
A dental gypsum slurry includes water and a dental gypsum powder containing hemihydrate gypsum and a polycarboxylic acid salt-based water-reducing agent, wherein a powder-water ratio of the water to the dental gypsum powder is 0.24 to 0.50, and when the water and the dental gypsum powder being mixed are poured up to a height of 50 mm in a cylindrical mold having an inner diameter of 35 mm, which is vertically placed on a flat surface, and then, the cylindrical mold is pulled upward at 10 mm/s at 30 seconds after start of mixing so that a mixture spreads planarly, the diameter of the mixture is 141.4 mm or more.
