DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to improve the strength after drying (green strength) of a glaze as well as the dispersion stability of the glaze. However, in the present invention, a polymer emulsion is added to the glaze in order to improve the strength after drying (green strength), but the glaze contains various types of electrolytes, thereby increasing the polymer emulsion. The emulsion may become unstable and may even aggregate. There are methods such as dipping, pouring, and spraying to apply a glaze to a ceramic base, but if the added polymer emulsion becomes unstable, the dispersibility of the glaze decreases, resulting in uneven glazing.
Furthermore, if the polymer emulsion aggregates, there will be a problem that glazing will not be possible. For this purpose, the glaze is made alkaline to stabilize the polymer emulsion and improve the dispersibility of the glaze.

The polymer emulsion is added and mixed into the glaze under alkaline conditions. The pH value of the glaze composition thus obtained is preferably 9 or more, more preferably 10 or more. The alkaline state can be achieved by adding an alkali such as awamonia, caustic soda, caustic potash, or amine to the glaze, or by adding these alkalis before or after the production of the polymer emulsion. Furthermore, when the glaze itself is sufficiently alkaline, it goes without saying that addition of alkali is unnecessary.

Since the present invention has the above configuration, the polymer emulsion in the glaze composition is prevented from agglomeration and stabilized in an alkaline state, thus improving the dispersibility of the glaze and exhibiting good glazing workability. When a polymer emulsion is added to a glaze, the strength of the glaze layer after applying the glaze to a ceramic base and drying, that is, the strength and water resistance of the raw glaze before firing, is improved, and the raw glaze and fabric or fabric are improved. This improves the adhesion between the top glaze and the bottom glaze or middle glaze, which prevents the glaze from peeling or chipping, significantly improves the surface finish, and prevents the occurrence of defective products. . Therefore, an important effect of the present invention is that it becomes possible to perform painting by so-called "on-glaze" in which the raw glaze is directly painted and fired.
By making the glaze alkaline, agglomeration, which is a major problem when adding polymer emulsion to glaze, is prevented, the polymer emulsion in the glaze is stabilized, and the dispersibility of the glaze itself is improved. This improves the workability of glazing.
