[Iroe (polychrome pottery)]
A technique of decorating ceramics.
Iroe refers to painting motifs or patterns using lead-based red, yellow and green color glazes on the surface of glazed and fired earthenwares, porcelains, and firing them again at a lower temperature (around 800 degrees C) so the colored glaze melts onto the underglaze.
Arita ware is one of the representative iroe ceramics in Japan.
