Hmm, you can see the base in the first post - it's highly polished, flat and smooth.
Not a common feature of Chinese glass - but it is a very recent feature which I have started noticing in TKMaxx when I go for a nosey to see how well they're progressing.
I've got a massive combed Chinese vase, I do think this does look to be of rather better quality.
For a start - the colours have been chosen, not randomly grabbed at! :ooh:
