PROBLEM TO BE SOLVED: To provide a ceramic product which is usable in being directly put over a fire and a method for manufacturing it. SOLUTION: This ceramic product is produced by adding tourmaline powder to a clay having silica and alumina as the main component in the raw material, followed by kneading the mixture, forming into desired shape, biscuit firing, glazing and firing, wherein the clay includes petalite, the addition level of tourmaline is 2 to 4 pts.wt. to 100 pts.wt. of the clay. The average particle size of the tourmaline powder is preferably 0.5 to 5μm. This method for manufacturing the ceramic product comprises the steps of preparing a clay including petalite, adding 2 to 4 pts.wt. of tourmaline powder to 100 pts.wt. of the clay and mixing, adding water to the mixture and kneading to make homogeneous, forming the kneaded mixture into a desired shape, drying, biscuit firing, glazing and firing. The ceramic product obtained by the method has deodoring effect, ion generating effect, etc., and suitable for an eathenware pot or a ceramic slab.
