Recently i bought some teaware from T2
example like this one http://www.t2tea.com/en/uk/teawares/t2- ... color=Red
Some of them are porcelain, some of them are fine bone china. The one in the picture doesn't have overglaze, but some do have colourful overglaze (?) and metallic rims like this one http://www.t2tea.com/en/uk/teawares/tea ... BA939.html
Then i stumbled upon some info regarding lead in teapot paint / glazing.
I'm quite worried as all of their teawares are very colourful, in all sorts of colours like red / yellow / even metallic-ish rim.
3 questions:
1. Just wondering, if I should be concerned about lead leeching from these products?

2. Is fine bone china better than porcelain in terms of chance of lead leeching?
3. Is pure white glazed ceramic teapot 100% sure without lead?
Thanks very much, your advice much appreciated!!
