This makes it possible to produce a heat-resistant tableware for flame-grinding, which is excellent in adhesion between the glaze layer and the substrate and excellent in strength.

According to the second modification, in addition to the first basalt glaze and the second basalt glaze, a third basalt glaze can be further prepared. The composition of the third basalt glaze may be different from that of the first basalt glaze and the glaze raw material powder used in the production of the second basalt glaze. Specifically, the third basalt glaze may contain more feldspar than the first and second basalt glazes. Accordingly, the third basalt glaze may have a relatively high heat resistance. According to a second variant, the step of applying the basalt glaze to the substrate comprises the steps of applying the first basalt glaze to the substrate, drying the substrate to which the first basalt glaze has been applied, Drying the base material with the second basalt glaze; and applying the third basalt glaze to the dried base material, and applying the third basalt glaze to the third basalt glaze, And drying the processed substrate. Accordingly, the substrate may have a structure in which the first basalt glaze layer having excellent adhesion with the substrate, the second basalt glaze layer having excellent strength, and the third basalt glaze layer having excellent heat resistance are sequentially stacked on the substrate Lt; / RTI > This makes it possible to produce a heat-resistant tableware for flame-grinding, which is excellent in adhesion between the glaze layer and the substrate and is excellent in strength and heat resistance.

The first mixed basalt glaze can be applied to the substrate after the first basalt glaze is used and before the second basalt glaze is used. Accordingly, a first mixed basalt glaze layer may be provided between the first basalt glaze layer and the second basalt glaze layer, whereby adhesion between the first basalt glaze layer and the second basalt glaze layer Can be improved.

According to the fourth modified example, in the second modified example described above, the first mixed basalt glaze mixed with the first basalt glaze and the second basalt glaze, and the first mixed basalt glaze mixed with the second basalt glaze and the third basalt glaze, A second mixed basalt glaze can be further prepared. As described above, the first mixed basalt glaze may be applied to the substrate before the second basalt glaze is applied after the first basalt glaze is used, and the second mixed basalt glaze may be applied to the second mixed basalt glaze, After the basalt glaze has been sown, the third basalt glaze may be slaughtered prior to use. Accordingly, a first mixed basalt glaze layer is provided between the first basalt glaze layer and the second basalt glaze layer, and a second mixed basalt glaze layer is provided between the second basalt glaze layer and the third basalt glaze layer Whereby adhesion between the first and second basalt glaze layers and the second and third basalt glaze layers and the third basalt glaze layer can be improved.

According to the fourth modification, after the basalt glaze-treated substrate is fired, a further heat treatment process may be further performed in a gas atmosphere containing nitrogen. Thus, the crystal structure of the heat-resistant tableware can be more stabilized.

Unlike the above-described embodiments and modifications of the present invention, when a glaze is manufactured using a conventional chemical agent such as iron oxide or manganese, it is developed into blackish brown.
