In the case of a ceramic dish, since it is sometimes put into water from an oven at 250 ° C., high thermal shock resistance is required. Therefore, it is necessary to keep the coefficient of thermal expansion of the material of the ceramic dish low, and it is required that the glaze used for the ceramic dish also has low thermal expansion. In addition, when the antibacterial agent is dispersed in the glaze, the thermal expansion increases, making it difficult to increase the adhesion between the ceramic base material and the glaze, and causing a problem that the glaze is vulnerable to thermal shock. To this end, the present invention has a configuration in which the glaze has two layers and the upper layer has a ceramic dish using glaze mixed with an inorganic antibacterial agent. With this configuration, the lower layer glaze can maintain the thermal shock resistance of the ceramic dish, and the upper glaze can have antibacterial properties, thereby improving the adhesion to the ceramic. In addition, it became possible to apply antibacterial treatment to a ceramic dish coated with glaze that has not been subjected to antibacterial treatment, so that the presence or absence of antibacterial treatment can be selected later.

Further, when an antibacterial agent is blended in the glaze, the glass component covers the surface of the antibacterial agent during firing, making it difficult for the antibacterial agent to be exposed on the surface of the coating film, resulting in a decrease in antibacterial performance. Therefore, in the present invention, by blending an inorganic antibacterial agent having a high elution property, even when the antibacterial agent is embedded in the glass of the glaze, the silver component in the antibacterial agent is eluted and the antibacterial agent is exhibited. I made it possible.

After inoculating Escherichia coli and Staphylococcus aureus on the surfaces of the above antibacterial products 1-4 and the additive-free products, the surfaces were wrapped with a film, and the number of viable bacteria after holding at 37 ° C. for 24 hours was measured. The measured results are shown in (Table 1). As shown in (Table 1), the antibacterial product 4 has lower antibacterial performance than other antibacterial products.
This is probably because the amount of the antibacterial agent exposed on the surface is small. Antibacterial product 1 and antibacterial product 2 do not change the amount of antibacterial agent exposed on the surface, but use a high-eluting antibacterial agent that carries silver ions on a ceramic composed of silica, boric acid, and calcium. It is considered that the antibacterial performance is high.

A 5% suspension was prepared by adding a silver zirconium phosphate antibacterial agent to pure water, subjected to isothermal shaking at 60 ° C. for 1 hour, and then filtered through a membrane filter having a pore size of 0.01 μm. When the Ag + concentration was measured, it was 0.01 pp.
m or less. The Ag + concentration of the antibacterial agent in which silver ions were carried on a ceramic having a composition of silica, boric acid and calcium was measured in the same manner and found to be 80 ppm. As can be seen, the dissolution of silver ions differs depending on the antibacterial agent, which affects the antibacterial performance when added to the glaze. If the antibacterial agent with a small elution property does not come out on the surface of the glaze, it does not come into contact with bacteria and the like, so that it is difficult to exhibit antibacterial performance. Antibacterial agents with high elution properties exhibit antibacterial performance because the antibacterial agents are exposed on the surface.
