This process causes the pigments to sink into the glaze, creating a unique, deep navy blue expression. This technique is particularly striking because of Okura Toen's "white" porcelain, which is renowned worldwide. Because the pigments are dissolved into the glaze, the surface is glossy and smooth. You can use it for a long time without any change. There is some gold fading on the rim of some cups. Otherwise, there are no noticeable scratches or stains.
