Thanks for fixing those Keith!
The bowl is rather thick, the dolphins and turtle are graal and bubbles are cut on the surface.
I took the photos at the Exhibition in 2005, which is why they're not really very good and have busy backgrounds - I was not rearranging the glass.

I can still see the dolphin bowl and the seal vase if I go to the Museum.
Here are a couple of pics of the Wave Form I have. He has since developed those into really tall things that look as if they are going to overbalance, and has omitted the graal figures inside.
I have been told he has an unfortunately high failure rate while making these - they are incredibly difficult to get to work and balance.
