SANITARY EARTHENWARE AND MANUFACTURING METHOD OF SANITARY EARTHENWARE
To provide a sanitary earthenware capable of enhancing "depth", and a manufacturing method of the sanitary earthenware.SOLUTION: There is provided a sanitary earthenware 1 having an earthenware base material 10, an upper glaze layer 30 positioned on a surface of the sanitary earthenware 10, and an intermediate layer 20 positioned between the earthenware raw material 10 and the upper glaze layer 30, and having percentage of area of air bubbles based on area of a cut surface by cutting the upper glaze layer 30 in a thickness direction of 3% or less. It is preferable that average air bubble diameter of the air bubbles at the cut surface is 50 μm or less. It is preferable that the number of air bubbles at the cut surface is 120 or less per 1 mm.SELECTED DRAWING: Figure 1
【課題】本発明は、「深み」をより向上できる衛生陶器及び衛生陶器の製造方法を目的とする。【解決手段】陶器素地１０と、陶器素地１０の表面に位置する上釉層３０と、陶器素地１０と上釉層３０との間に位置する中間層２０とを備え、上釉層３０を厚さ方向に切断した切断面の面積に対する気泡の面積の割合が３％以下である、衛生陶器１。前記切断面における気泡の平均気泡径が５０μｍ以下であることが好ましい。前記切断面における気泡数が１ｍｍ２当たり１２０個以下であることが好ましい。【選択図】図１
