The invention relates to a method of making a sink comprising: cutting out material that will constitute a bottom of the sink; making a hole for a drain in the bottom of the sink; supporting the edges of the bottom of the sink on a flat support and applying a mechanical force on the rim of the hole for the drain in the bottom of the sink; subjecting the bottom of the sink to a gradual and stepwise heating such that the mechanical force applied deforms said surface; cooling a flat slab; placing additional flat slabs around the first slab, on the sides thereof, to constitute the sides of the sink; externally coating the assembly made with a reinforcement comprising resins, glass fiber, mineral fillers, etc.; and bonding the upper part of the assembly made with the countertop where the sink is located.

To provide a dental porcelain paste which can maintain maintaining the paste state and have excellent application property for a long period of time and hardly causes carbonization or bubbles due to the influence of an organic component or a polymer component during firing. The present invention provides a dental porcelain paste for preparing a dental prosthesis device, comprising: 50.0 to 80.0 wt. % of a glass powder (a) having a maximum particle diameter of 100 m or less and an average particle diameter of 1 to 20 m, 0.5 to 10.0 wt. % of a hydrophobized fine particle silica (b) having an average primary particle diameter of 1 to 50 nm, and 10.0 to 49.5 wt. % of an organic solvent (c) having a boiling point it is within (bp) of 100 to 300 C.
