I should be thrilled to have finally received my shipment of materials, but
I looked at the label and knew I just couldn't accept them. In the catalog
the Amaco crystaltex glazes were coded with "1" which means lead-free and
ok dinnerware. When the the MSDS sheets arrived, some had lead borosilicate
and the "HL" label. How can something with lead borosilicate be labeled
with "1"? I phoned the company to tell them I did not want those glazes,
but they arrived last Friday. The supplier also stated that some of the
MSDS sheets were outdated; the glazes have been re-formulated without lead.
Why did they send MSDS that were not current? I asked for the new ones.
They have not yet arrived and this was at least 2 weeks ago.

After talking with the AP in charge of materials and safety and the
district person in charge of risk management, I will contact the company
again and tell them that I refuse the shipment.

Am I being too uptight? Silica is already a problem, and I have discussed
with my students ways to keep exposure limited (no gum for starters). But
how can I supervise 34 - 36 students at all times when I need to help some
of them individually?

Thanks to Bob Fromme and Ruth Lodek for the advise. I tried the URL to
ASTM's site, but it looked too technical for my needs.

Thanks in advance to all who reply,
Julie

If I fear to do the right thing,
I'm in the wrong place.
