Title:
METHOD FOR BAKING CERAMIC AND DECORATIVE PICTURE FRAME USING THE CERAMIC
Document Type and Number:
Japanese Patent JP2000355013
Kind Code:
A
Abstract:

To create a ceramic with high artistic properties by adding silver to a surface layer part of clay of a desired shape and boosting temperature to a level within a specified range to bake the clay in an atmosphere and thereby imparting the reducing action of the silver to the surface layer of clay.

A clay is molded into a desired shape and a silver clay 11 to the surface of which silver is added is imbedded at a desired spot on the surface layer part 10f of the molded clay or is applied to the spot. Further, the clay with added silver is gradually heated up using an electric furnace by setting the heating of both upper and lower electrically heated wires low and increasing the internal temperature of the furnace to about 150°C taking time for about 1.5 hrs. Next, the heating of only the lower electrically heated wire is set high and then the clay is gradually heated up until the internal temperature of the furnace reaches about 300°C taking time for about 1.5 hrs. After that, the heating of the upper electrically heated wire is also set high and further, the internal temperature of the surface is gradually increased until it reaches about 1,200-1,300°C taking time for about 7 hrs. Thus the clay is exposed to this heating process to be baked, and the reducing action of the silver is imparted as far as the surface of the clay.
