Hi Joe,
I can't speak for anyone else but I'm having trouble with the description as a Goblet. Goblets evoke images of something to drink out of and are not normally lidded, yes I know German Steins are.
Then again the dimensions you give are too big to call it a turned box, I've therefore got to see it as a lidded vessel, but as I said, that's just me, and as always I'm prepares to be disagreed with.
As for the turning and design, whatever you want to call it, it's well up to your normal high standards and a joy to look at and think about the processes you've used in it's making,
thanks for posting.
