IMPORTANT: *The following Potter's Choice glazes, PC-12, 20, 21, 23, 27,
28, 31, 33, 34, 37, 39, 43, 55, and 57, continue to be AP in their liquid form
(pints and gallons) and carry the AP seal.
There has been a change to the
labeling of the 25# dry dipping forms of these glazes. That labeling will no longer carry the AP seal but will include the
wording "CONFORMS TO ASTM D-4236". The following statement has also
been added to the label: "WARNING: This product contains a chemical known
to the State of California to cause cancer." PC-25, 42, 46, and 49 remain
CL and now have this warning statement.
This change satisfies California Proposition 65
labeling requirement for titanium dioxide.
This only applies to dry forms of
the material that are unbound in a non-dusting matrix (like water, oil, etc.).
