    摘要： Sanitary wares having a controlled surface are disclosed which are less likely to be stained or soiled and/or possess excellent gloss. The first sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a center line average roughness Ra of less than 0.07 µm. This sanitary ware is advantageous in that stains or soils are much less likely to be adhered to the surface thereof and, even when adhered to the surface thereof, can be removed by a weak water stream. The second sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a kurtosis Rku of less than 2.70. This sanitary ware advantageously possesses excellent surface gloss. The third sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface of the surface glaze layer consists essentially of a vitreous component and is free from silica particles having a particle diameter of not less than 10 µm. This sanitary ware is advantageous in that stains or soils are less likely to be adhered to the surface thereof.
