Its glaze color is cyan white and elegant, the glaze surface is clear and clean, the embryo material is firm and greasy white, and the color is warm and moist like jade, so it has been known as a "fake jade artifact" in history. It is called shadow celadon because its body is fine and clean, its glaze is green and translucent, and its shadow can be seen in light. While the glaze color is white with flashing blue, and white with green, which is between blue and white. Its texture is like sapphire, so it is also called "celadon porcelain". During the Northern Song Dynasty, it was founded and burned in Jingdezhen, with Hutian kiln products being the best. Kilns in Jiangxi, Anhui, Guangdong, Zhejiang, Fujian, and other places are all fired. The iron content of the shadow blue porcelain body is less than 1%, and the iron content of the glaze is about 1%, which is similar to the iron content of the white porcelain glaze in the same region. However, the color of the glaze is not white but bluish white or aqua green, because the shadow blue glaze is more transparent and the glaze layer is thicker.
