Claim Text:
1. A sanitary ware comprising: a sanitary ware body; and a sole glaze layer provided directly on the sanitary ware body such that an inner surface of the sole glaze layer contacts the sanitary ware body and an outer surface of the sole glaze layer is also an outermost surface of the sanitary ware, wherein the sole glaze layer has a single layer structure which includes a phase-separated glass as a major part thereof, the glaze layer having a surface roughness Ra of not more than 0.07 μm and a thickness of not less than 0.3 mm, the surface of the glaze layer has a lightness L* of not less than 85, particles of the phase-separated glass in the single layer structure have an independent liquid droplet structure (binodal) or an entanglement structure (spinodal), when the particles have an independent liquid droplet structure (binodal), a diameter of the liquid droplets is not less than 150 nm; and, when the particles have an entanglement structure (spinodal), a mean width of branches in the entanglement structure is not less than 100 nm.
