It is difficult to require such labor every time. In particular, among sanitary wares, there is a strong desire for users to reduce the frequency of cleaning, if possible, of toilet bowls, urinals, and toilet sana. Furthermore, in recent years, there has been a problem of river pollution due to the drainage of household wastewater containing the surfactant. Therefore, an object of the present invention is to provide a sanitary ware which is capable of easily removing dirt on the surface of the sanitary ware with running water without using a surfactant and without rubbing strongly with a scourer or a brush. With the goal.

防汚性衛生陶器を提供する。According to the present invention, in order to solve the above-mentioned problems, a glaze layer is coated on the surface of a ceramic body,
The glaze layer contains at least a glassy component, and the glassy component contains at least a SiO 2 component, an Al 2 O 3 component, a divalent metal oxide component, and an alkali metal oxide component, and the weight of the SiO 2 component Is 55 to 80% with respect to the total weight of the glass component, the weight of the Al 2 O 3 component is 5 to 13% with respect to the total weight of the glass component, and the weight of the divalent metal oxide component is The weight of the alkali metal oxide component is 1 to 7% with respect to the total weight of the glass component, and the divalent metal oxide component is at least MgO. A toilet bowl comprising a component, a CaO component, and a ZnO component, wherein the amount of the MgO component is 10 to 30 mol% based on the total amount of the divalent metal oxide component.

Vに近いものほど汚れにくいと考えられる。[0005] If the amount of the MgO component in the glaze is at least 10 mol% with respect to the total amount of the divalent metal oxide components in the glaze, the surface charge state of the substrate surface will probably change, Dirt is less likely to adhere in the use environment. In particular, in toilet bowls, urinals, and toilet sana, the zeta potential of the surface at pH 7 to 9, which is the use environment, is -2.
0 mV to -60 mV, more preferably -30 mV to -5
At about 0 mV, the effect is remarkable because it is probably the same sign and the same as the zeta potential of the adhered dirt surface. It is known that proteins, urine stones, Escherichia coli, etc., which are typical stain components, are generally negatively charged. For example, since the zeta potential of Escherichia coli at pH 7 to 9 was around -40 mV, The material surface has a negative zeta potential and the value is -40 m
It is considered that the one closer to V is less likely to be stained.

Then, Dental plaque dye gel "DENTCL" made by Healthtech
A solution obtained by diluting "UB" with distilled water was sprayed into a ball, and the adhesion amount of urinary stone was evaluated based on the intensity of the red color. When this plaque-stained gel is used, a portion having a large amount of urinary stones is strongly dyed red, and a portion having no urolith is not colored. Therefore, it is possible to visually evaluate the attached amount of urinary stone. As a result, it was found that the diluted urine draft part and the immersion part in the ball were strongly stained red, and that a large amount of urine stones had adhered.
