Reputed as a "manmade gem", color-glazed porcelain looks brilliant and seems to carry many connotations. Thanks to new scientific measures for allotting ingredients and controlling kiln temperatures, craftsmen have not only managed to improve the quality of color glazes and find formulas for different products, but they have also successively created more than 100 glaze colors and several kinds of lusterless colored glazes.

Generally speaking, color-glazed porcelain falls into the following categories: blue, dark reddish, black, white, yellow, green, blue-and-white glazed, and so on, with each color further subcategorized into specific type.

Collectors of different types of color-glazed porcelain should keep one thing in mind: The classification of color glazes cannot be judged based on the color of a glaze surface with the naked eye. For instance, although some blue-and-white glazes produced in kilns in Fujian Province during the Song Dynasty appear to be white, the proportion of different microelements classifies them as white-and-blue glazed porcelain.
