I intend to have one of my glazes, which has barium in the recipe,
tested for leachability at our local government testing laboritories, but
was very surprised to be told on the phone that there is actually no
Australian standard for barium 'leachability' (they can test my glaze and
give me a result however). I'd be very grateful to know what a safe
amount is, according to standards in other parts of the world if they are
available. Thanks, Denise.
