As reported a few months ago, I used thick cadmium-encapsulated stains on
a bowl, covered with a very light coat of clear. It tested OK when I sent
it to Alfred.
If I wanted to use a glaze with a % of cadmium, I'd do a test bowl with
the glaze plain, and one with a light coating of clear over the glaze, and
send both to be tested. Best wishes, Lesley.
