Has anyone got the information on the typical leachate concentration is in
mcg/dl for a typica worst case scenario for barium?
Also, do we know what the epa regulations are for barium release in glazes? I
have the numbers for water but can't find anything relating to ceramics.
I've been having a interesting discussion with someone on this who seems to
have quite a lot more knowledge than I in these matters and he just can't see
that Ba alumino silicates as being very dangerous. He requested that I ask the
list about the typical leachate concentrations as mentioned above.
I checked out the EPA site and found a paper on Barium toxicology but it was
in pdf format and after an hour of downloading it I got an error message and
could only print out the title page. AARGH!
Also, has anyone had any of their barium glazes tested, and if you have could
you please post the results to the list.
Thanks!
Warm regards,
June

Any good testing lab should have info on the govt regs for Ba release.
