I believe he was talking about just a glaze as Kato's. I'd be happy to sign it. 9.8cm.tall and 8.7cm.across. Assorts of Dong Son Bronze Axes. The patina is very nice with Green and Blue colors.
Condition is excellent, no crack, no restoration.
Ando has had a prolific career producing some fine Shino and Ki-Seto works. Ando is especially noted for the whiteness of his Shino as so well exemplified here. 24.8cm.tall and 12.3cm.across- signed on base 'hi' for Hidetake. The tea masters of the early Edo period actually loved Irabo chawan which, like so many styles, have their origin in Korean pots. It's a very well-loved style even today, although very few potters make it.
