SANITARY WARE
A sanitary ware includes a base, and a glaze layer formed on an outer side than the base. In color representation by the Lab color system, an absolute value of a difference (ΔL) between an L value obtained from observation of a part with the glaze layer formed thereon and an L value obtained from observation of a part with the glaze layer substantially unformed thereon is not more than 12, or a color difference (ΔE) between a color in observation of the part with the glaze layer formed thereon and a color in observation of the part with the glaze layer 5 substantially unformed thereon is not more than 14. Even though the thickness of the glaze layer varies so that the color of the base may be shown more or less through the glaze layer, there is almost no difference in color seen from the glaze layer side.
