Mizuno Norio was born in Seto in 1950 and has been accepted at
the Nitten exhibition on 34 occasions since 1973. In 2010 he was designated as an Intangible Cultural
Asset of Seto City, Aichi Prefecture. This chawan has his incised signature outside
the foot ring, as shown in the last photograph. In recent years Mizuno has
specialised in nerikomi (a marbling technique) but
this teabowl, although unused, dates back to around 1990.
