In the case of the tourmaline composition described in Japanese Unexamined Patent Application Publication No. 2002-129, Kibushi clay, Frogme clay and kaolin are used as clay, and a kneaded product obtained by kneading these clays with 5 to 50% tourmaline is: It is shaped into a lump or granular material and fired,
Although it can be applied as various fillers, it is difficult to mold it into products with complicated shapes due to poor moldability, and if various cooking utensils to be used by direct heating (for example, clay pots, clay bottles, Even if it is molded into a ceramic plate)
There was a problem that it broke when put on fire. Further, when firing at a high firing temperature (for example, about 1000 ° C.), there is a problem that the composition of tourmaline changes, and the excellent properties of tourmaline deteriorate or are lost.

とになる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the tourmaline-containing porcelain product of the present invention will be described. The pottery product of the present invention contains silica and alumina as main components, and 100 parts by weight of clay containing petalite contains 2 to 2 parts of tourmaline powder.
4 parts by weight, preferably 2.5 to 3.5 parts by weight, such a pottery product is obtained by kneading petalite and tourmaline powder until uniform to obtain a kneaded product having a desired shape. After molding, it is manufactured by firing, glazing, and firing. At this time, if the amount of the tourmaline powder is less than 2 parts by weight based on 100 parts by weight of the clay, cracking does not occur in the fired product, but the effect of the tourmaline addition is not sufficiently exhibited, and conversely, If the compounding amount exceeds 4 parts by weight, various effects due to the addition of tourmaline are sufficiently exhibited, but the moldability is deteriorated, and cracking occurs when the molded product is fired.

かけてもヒビ割れが生じることもない。On the other hand, the petalite contained in the clay of the pottery product of the present invention is a tectosilicate mineral of lithium and aluminum (composition: LiAlSi 4 O 10 ), and its refractory temperature is about 1200 ° C., which is a clay base material. 30-7 in
0% by weight, preferably 35 to 60% by weight, when compared to a base such as Kibushi clay, Frog eye clay or kaolin,
Moldability and heat resistance are improved, and a molded product that does not crack even when fired is obtained. This is probably due to the fact that petalite contains more silica and less alumina than the common clay, Kibushi clay and Frogme clay.
It is considered that this is due to the fact that a certain amount of LiO 2 is contained as another main component. Clays suitable for producing the pottery products of the present invention include Petalite 30-
70% by weight, Frog eye clay 20-50% by weight, Kibushi clay 10
-25% by weight. In the case of such a mixture, the properties of tourmaline are hardly deteriorated even when firing at high temperature, and cracking occurs even when the fired product is directly fired. It does not occur.

（Ａ〜Ｃ）に限定されるものではない。On the other hand, when a mixture of Kibushi clay and Frogme clay is used as a clay, a molded article having a complicated shape can be obtained even if it is kneaded with the tourmaline powder in the above-described amount. Although it is difficult to produce a fired product having a relatively simple shape, it can be cracked when used directly by burning. In addition, when Kibushi clay, Frogme clay, or the like is used as the clay, the firing temperature is limited to 950 ° C. or lower because tourmaline changes its composition at a temperature of 950 to 1050 ° C. Table 1 below shows specific chemical compositions of commercially available petalite powders suitable for use in the present invention, but the petalites usable in the present invention are limited to these three types (A to C). is not.
