SURFACE ADDITIVE DECORATION OF SANITATION TOILET FIXTURE

PURPOSE:To prevent collapse of a pattern by a method wherein after coating glaze, a pattern such as spots, a stone grain pattern, and others is processed on a surface of the glaze and when a product is prepared by burning, fluidity of the glaze in burning is so adjusted as to be within a specific range in a flow degree. CONSTITUTION:When a green compact is burnt to be made into a product, a glaze of which fluidity in burning is so adjusted to be within a range of 0.1 to 1.0mm in a flow degree is used. For instance, bright glaze is coated on an upper end part 12 of a surface of a green compact before burning of a western style toilet stool and besides, glaze (matte glaze)is coated on the other part. Then, a coloring agent, i.e. the coloring agent (liquid) prepared by adding cobalt pigment 3wt.% to the glaze 100 is applied thereon by spraying in a scattered point manner to form a spotted pattern. The glaze of which the flow degree is adjusted to almost zero by controlling concretely its particle size so that a residue when 1kg the glaze is passed through a 500 mesh sieve becomes 7 to 10g, is used. When the product is burnt under a specific condition, the dotted pattern on the surface is not collapsed at all.
