Does any one know where I can source some cobalt glass? I bought some 5 x5xcm pieces from Livingstone last year but tey were clear glass painted blue . The paint came off very quickly. I need the actual glass to be coloured blue for the flame tests. Any suggestions of suppliers welcome.

I found this on Google, after a bit of a search. No idea where they're based.

Try Labtek. It is on the catalog.
HAINES might help you even if the item is not on their catalog.
