Sanitary ware which strongly resists adhesion of dirt and which may be easily cleaned with a weak flow of water, over a long period of time, comprises a first coloring glaze layer formed on the surface of a ceramic body, a second transparent glaze layer formed on the first glaze layer, and an engobe layer formed between said body surface and said first glaze layer.

Sanitary ware and process for producing same

A method of producing a porous material having open pores including stirring a mixture including (i) an epoxy compound having at least one epoxy ring in the compound, (ii) a hardener capable of reacting with the epoxy compount to harden the epoxy compound, (iii) a filler and (iv) water to form an emulsion slurry having a low viscosity and containing the soluble salts uniformly dispersed therein, casting the resulting emulsion slurry in a water impermeable mold and then hardening the slurry while maintaining the water content thereof, and wherein the soluble salts are added to the mixture. The method makes it possible to produce a large scale porous material having open pores and a complicated shape whose shrinkage factor during hardening and water and air permeabilities are controlled to desired levels respectively while scattering thereof is reduced.

Method of producing porous material having open pores

A filler for patterning of ceramics product, comprising a slip composed mainly of a ceramics base material having a binder and a pigment added therein formed into particulate.
