I really appreciated the advice I received from this list when I inquired a=
bout setting up my backyard studio in regards to kiln placement.
Now I have a question about commercial glazes.
I purchased a couple of kilns from a government-run work program that had l=
ost its funding and was closing down.
Included with the kilns were boxes and boxes of glaze and jugs and jars of =
glaze and more boxes of glaze.
I'm not sure how old this stuff is, and I'm about to sort through it to det=
ermine what I'll keep.
Are there certain brands / types of commercial glazes that I should avoid, =
and throw into the 'discard' pile immediately?
Were there any relatively-recent safety standards put in place for commerci=
al glaze manufacturing that some of these jugged 'n' jarred 'n' boxed glaze=
s might not adhere to?
As always, I appreciate the sage advice.

Hi Steven,
Best to find out which have toxic materials in them - perhaps you can
get Material Safety Data Sheets from the various companies.
You may have some lead glazes.
