I ran it through my version of Insight, using the ingredients your listed,
and it's pretty well within their limits for a cone 10 glaze. The silica came
out about 3.46 (minimum is stated as 3.5). None of the RO column ingredients
is out of kilter, and the alumina and silica are just about within range.
I think that 5% barium in a gloss glaze like this is probably OK, but if you
want to be sure, send it off to Alfred to be tested.
