Thanks guys,
the scratches in the bottom were made when I passed it round for others to look at, it is after all just an experimental piece.
The bit I'm not overly happy with is around the rim of the bowl and the edges of the ring on the lid. I did try making a shallow groove and filling it with GL and then cutting it back on the lathe, like you do when putting a stained line in, but it just seemed to pull the GL out.
It's not put me off though, I will try again soon.
Regards
John
