(57) [Summary] [Problem] When an antibacterial agent containing silver as an antibacterial component is applied to make glazed porcelain articles antibacterial, silver is scattered and evaporated during firing and is lost from the surface part. Thus, problems such as a decrease in antibacterial ability or a discoloration of silver to yellow and impairing the appearance quality of ceramic articles are solved. When a glaze layer is provided on the surface of a ceramic body and fired to obtain a glazed ceramic article, A layer 12 of an antibacterial agent containing silver as an antibacterial component is applied to the lower side of the glaze layer 14 on the outermost surface and on the surface of the ceramic body 10, and then baked. At the time of firing, the antibacterial agent is transferred to the surface by utilizing the phenomenon that the antibacterial agent diffuses and moves into the melted glaze, and the glazed ceramic article is given antibacterial properties by the antibacterial agent that reaches the surface. |
