I would like to comment on these glazes. As a high school teacher, I am
always concerned about safety. Mine - is most important to me. Poisons that
can be absorbed or inhaled are always a concern. Then there is the issue of
girls who are pregnant and don't know it yet to even warn you.
Many of these chemicals are very toxic if not handled properly. Please use
extreme care especially with the
Barium carbonate. I will not even keep it on campus.
Kids are kids. And we all tend to put our bare hands in too many things
that we shouldn't.
Please check on the proper way to use and store these chemicals for your
Madera High School
These are reliable glazes that work well with many possibilities. If you
need more information, let me know. Carole Iacovelli
