Irabo teabowls were made to order for Japanese tea masters beginning in the early 17th century. Japanese collectors admired the rustic quality of the surface imperfections. This type of bowl is characterised by a coarse, stone texture and ochre-coloured glaze. Bowls of this type were replicated at various kilns in Japan, including the Karatsu kiln in northern Kyushu and the Rakuzan kiln in Matsue.
