とはない。In the glaze composition of the present invention, the content of the silver-containing substance is 0.01 to 1% (weight) in terms of metallic silver.
It is. If the content of the silver-containing substance is less than 0.01% by weight, the antibacterial and antifungal properties of the obtained glaze layer may be insufficient in practical use, and if it exceeds 1% by weight, An excessive amount of the antimicrobial component is not only economically disadvantageous due to an excessive amount, but also may give undesired changes in the color and material of the obtained glaze layer. In general, when the content of the silver-containing substance (in terms of silver) is within the range of 0.01 to 1% by weight, the handleability, coating properties, and color and material of the glaze layer are significantly adversely affected. Will not give.

活性化し、これが殺菌効果を奏するものと考えられる。[0011] The glaze layer formed from the glaze composition of the present invention exhibits practically excellent antibacterial and antifungal properties, even though the addition amount of the antibacterial component is only 0.01 to 1% by weight. It is considered that silver on the surface of the glaze layer activates oxygen existing in the vicinity thereof, and this has a bactericidal effect.
【００１２】釉薬層中における銀含有物質の存在態様と
しては下記の２種が考えられる。すなわちその一種にお
いては銀含有物質が、釉薬層中のガラス相（非結晶性）
中に含まれる場合であり、他の一種においては、銀含有
物質が釉薬層中の結晶相中に含まれる場合である。The following two conceivable modes of the silver-containing substance in the glaze layer are considered. That is, in one kind, the silver-containing substance is the glass phase (amorphous)
In another type, the silver-containing material is included in the crystal phase in the glaze layer.
【００１３】銀含有物質として、銀担持イオン交換性化
合物を用いた場合、得られる銀含有物質は釉薬層中の結
晶相中に含まれる。しかし、他の銀含有物質は、釉薬層
中のガラス層中に含まれる。When a silver-carrying ion-exchange compound is used as the silver-containing substance, the obtained silver-containing substance is contained in the crystal phase in the glaze layer. However, other silver-containing materials are contained in the glass layer in the glaze layer.
【００１４】得られる釉薬層の抗菌・防カビ性は、銀含
有物質が結晶相中に含まれている場合の方が、ガラス相
中に含まれている場合よりもやゝ優れている。これは、
結晶相中に含まれている銀担持イオン交換性化合物中の
銀の方が、ガラス相中に含まれている銀よりも、高い活
性度を有するためであると考えられる。The antibacterial and antifungal properties of the obtained glaze layer are slightly better when the silver-containing substance is contained in the crystal phase than when it is contained in the glass phase. this is,
This is considered to be because silver in the silver-supporting ion-exchange compound contained in the crystal phase has higher activity than silver contained in the glass phase.
【００１５】しかし、結晶相を含む釉薬層は、結晶相を

明性を要求され、従ってガラス相を主体とする釉薬層を
形成する場合には、銀担持イオン交換性化合物の利用に
格別の利点はない。However, a glaze layer containing a crystal phase has a problem that transparency is lower than that of a glaze layer consisting only of a glass phase without containing a crystal phase. Therefore, when a high transparency is required, and thus a glaze layer mainly composed of a glass phase is formed, there is no particular advantage in the use of the silver-supported ion exchange compound.
