strapping.

I assumed psychadelic colours.

That is cobalt.

Even in that pic you can se the blues are different, your bowl teal, the tall pot is cobalt. (I think vase is too common a word for it. I call them pots, in recognition of Chinese paint pots.)
I see you have an envelope, Look out for a message from the board so we can get in email contact so I can send you the pics of the "hat". I couldn't work out what it was for ages. With the big band of thick glass under the rim, it reminded me of a hat. Perhaps when you get the pics, you might be able to resize them to put here?
It would be really appropriate to have that illustrated here, beside your completed Zig-zag in all its glory. I have never actually seen a bowl in reality.
There is a drawing of one in some official early blurb.

Even a damaged attenuated strapped bottle is worth having. You just have to consider the damage part of the history and that a damaged one is far better than none at all.
Michael Harris technical skills developed very rapidly indeed, he did have an innate talent for the work, but what I love most is that even in the wonkiest, crudest bits, the art shines out from within.
