We recently had this discussion within the EtsyMudTeam. Here is some more info/testing sources (originally posted by Jen Wolfe):
Alfred Analytical Laboratory
Location: Alfred Station, NY, USA
Will do leach testing for extractable metals in fired glazes. Contact Dr. Roland Hale, Director, Alfred Analytical Laboratory, 4964 Kenyon Road, Alfred Station, NY 14803
Informative links ...
Massive list of testing labs. Some non-USA labs are listed.
Calm and clear article on glaze testing from Big Ceramic Store. It will help you understand what to test for.
