Yukirinsai is one of the most painstaking pottery techniques. First, the glaze of the base color is applied to the surface of the vessel to be fired. Then gold leaf id applied onto it and it is covered with another layer of the transparent glaze and further fired at higher temperature so that the gold leaf is effectively sandwiched between two layers of glaze.

This adds to the durability of the gold decoration and makes the glitter of gold more contained and elegant. As the beauty of the finished work solely depends on the simple combination of the gold leaf and transparent glaze, careful attention must be paid to the hue of the base color and the layout of the gold leaf. It also requires a highly specialized technique to ensure that the gold leaf doesn't roll up or melt into the glaze during firing.

All these meticulous care comes into fruition of a highly elaborate work with the gold leaf decoration looking as if it emerges up to the surface of the vessel. Although most of the pottery techniques used in Japan were introduced from China, this Yurikinsai technique was invented by the hands of Japanese potters. What covers the glitter of gold may be the Japanese veneration for modesty.
