Description

This technique originates from China and uses white stone to produce porcelain clay. Called seihakuji in Japanese, it is porcelain that has been bisque fired and painted with a glaze containing a small amount of iron, which turns a bluish tint when fired again. There is also hakuji (white porcelain), which is painted with a glaze that turns transparent when fired, and seiji (blue porcelain), made with clay that turns blue when fired. For celadon glaze porcelain, designs are inscribed on the piece, and after firing, bluish glaze that has collected in the indentations can look like beautiful pools of water. Great care must be taken with celadon because the glaze must be applied thickly, which places a strain on the porcelain and makes it tend to crack during firing.
