Iroe (literally color painting in Japanese) is a technique in which a transparent glaze is applied and the piece glost-fired, then paint is applied over the glaze and the piece is fired again at a low temperature of approximately 800 degrees Celsius. It is also called uwae, or over-painting. The paint used in traditional iroe is known as wa-enogu (Japanese-style paint), and color choices include red, blue, yellow, green and purple. It is also possible to use yo-enogu (Western-style paint).
Facts about iroe
Wa-enogu is traditional paint originally from China. The colors are dramatically different before and after firing. By contrast, with Western-style yo-enogu the color hardly changes after firing, the colors can be mixed, and there are numerous colors to choose from
