PROBLEM TO BE SOLVED: To obtain pottery improved in strength and capable of using for various uses by including carbon fiber into porous pottery in which pores are dispersed. SOLUTION: This pottery is obtained by mixing clay with resin filler and carbon fiber and kneading, forming and drying the mixture and baking the mixture and applying glaze and baking the glaze. For example, drying can be carried out by natural drying or forced drying and ungrazing may be carried out for 6-8 hr at 550-800 deg.C and baking can be carried out for 13-18 hr at 1,150 to 1,300 deg.C. For example, a hollow resin filler is used as the resin filler. In the above step, the resin filler is removed by burning and pores are formed in the part of the resin filler. In the carbon fiber, the content ratio may be different according to place, though uniform disperse of carbon fiber is generally preferable. A carbon fiber woven into fabric can be used in addition to fibrous carbon fiber as the carbon fiber. It is also preferable that disperse ratio of pores is low (or high) in the inside and high (or low) in the surrounding part. |
