In this case, the glaze is formed using jadeite powder. Since the powder has little plasticity, it precipitates immediately even when suspended in water, making it difficult to apply the glaze to the surface of the ceramic body. Therefore, the glaze contains Colemanite and bentonite. The content of colemanite and bentonite in the glaze layer 2 is preferably such that the content of colemanite is about 2 to 3% by weight and the content of bentonite is about 8 to 10% by weight.

Because it is 6 and hard, oils and fats are used for grinding. After the grinding, in order to remove the oils and fats, they are immersed in a 7% aqueous sodium hydroxide solution and repeatedly stirred and washed to remove the oils and fats. Since the jadeite powder thus produced has little plasticity, it is immediately precipitated even when suspended in water, and it is very difficult to produce a glaze and apply it to a pottery substrate. Therefore, it is preferable to add a Colemanite and a bentonite to jadeite powder and stir them to give a consistency, thereby producing a glaze. In this case, the content of colemanite and bentonite in the glaze is such that the content of colemanite is about 2 to 3% by weight and the content of bentonite is 8%.
It is preferably from 10 to 10% by weight.

If the content is more than 10% by weight, the viscosity of the glaze increases, and it may be difficult to apply the glaze to a ceramic substrate. Further, the glaze may contain other components usually contained in the glaze used when manufacturing pottery. Such components include, for example, quartz sand, feldspar, limestone, amorphous silica and the like.

The coating amount is preferably such that the thickness of the glaze layer after firing is 0.7 to 1.2 mm, and 0.9 to 1.1 mm.
It is more preferable that the coating amount is such that the thickness becomes as small as possible.
If the amount of application is such that the thickness of the glaze layer after firing is less than 0.2 mm, the aesthetic appearance of the resulting pottery may be inferior or the far-infrared effect may not be sufficient. Even if the thickness of the glaze layer exceeds 0.5 mm, the aesthetic appearance and far-infrared ray effect of the obtained pottery may not be further increased, so that it is preferable to be within the above range.
