Japanese craftsmanship

Not a very good picture of this rather strange glass covered container by Ishida Watari (Japanese National Treasure exhibiting at the Crafting Beauty in Modern Japan exhibition). It's made of
pâte de verre, with an incised regular pattern which I imagine is cut into the mould before packing it with glass. Incredibly delicate and exquisite craftsmanship that I just know I can never match up to. Apologies to the artist for taking this picture (don't think I should have) but I can't see that it matters. I couldn't copy it even if Iwanted to - and I don't. Only one out of 3 pieces in the exhibition.
