Production manner null of crystal chrysanthemum stone and crystal chrysanthemum

摘要

PROBLEM TO BE SOLVED: To produce a crystalline chrysanthemum-patterned stone tinged with a color by housing a glaze raw material and a metallic oxide in a container for production, heating both at a high temperature, then cooling the heated material, depositing a crystal of a chrysan themum pattern in a glaze and solidifying the resultant material. ;SOLUTION: This crystalline chrysanthemum-patterned stone is obtained by injecting a slip prepared by mixing a porcelain clay with Kibushi clay, water glass and water into a gypsum mold, calcining the prepared slip, then biscuit baking the calcined material at about 700°C, producing a box-shaped container 1 for production, then charging a glaze raw material obtained by mixing about 50wt.% feldspar with about 20wt.% ZnO, about 20wt.% frit, about 10wt.% quartzite, etc., and a metallic oxide selected from among oxides of Zn, Co, Mn, W and Fe into the container for the production, heat-treating the charged materials at about 1100-1300°C for about 40min, subsequently cooling the heated materials to about 1000°C for about 4hr, then naturally allowing the cooled materials to cool for about 50hr, solidifying the cooled material in the container 1 for the production and discharging a rough stone 5 for the crystalline chrysanthemum-patterned stone comprising chrysanthemum patterns 51, arranged and deposited on the glaze ground 52 from a kiln. Only the container 1 for production is then cut and removed by a grinder, etc., and the surface is polished to afford the crystalline chrysanthemum-patterned stone.;COPYRIGHT: (C)1997,JPO
