Hello all,
I have a glaze that I want to test for barium release. I contacted a
lab here in Dallas and they wanted to know which test to run: TCRP (acid
test) or SPRD (Die water test).
If anyone knows please let me know. Or If anyone knows a good lab that
runs those tests, I would appreciate the address/phone number. Or the
EPA?
The cone 10 glaze only has 4% Barium but as it is functional I would
feel better knowing it doesn't leach.
Thanks for your help,
