Hello clayarters,
Does anyone know of a site that will give some facts on lead - I have to give
a "persuasive speech" for a class. I want to convince my audience that they
should buy ceramics directly from the artist. I'm looking for the medical
symptoms, statistics & facts on lead poisoning, History on lead, federal &
state laws re lead in glazes, and stuff like that. It is only a 6 -8 min
speech so I just need enough facts to fill half of that.

Carol: You have a tall order to pack in all information into a 6-8
minute speech. I used to teach that subject. You have a great resource
next door. John Conrad teaches at Mesa College and is understands the
subject well. One lead hazards, the expert is Monona Rossol Art &
Theater Safety in NY. (212) 777-0062 <75054-2542.compuserve.com>.
Another person to talk with is Tom Hinds at Ducan Ceramics. In
California, the Cal/EPA Office of Environmentoal Health hazard
Assessment (OEHHA) has been assessing the effects of lead and cadmium
and, recently, arsenic. I worked with staff of the Calif. Dept. of
Health Services in 93 & 94 when AB 3659 required all folks making and
selling functional ceramics in the state had to pay the $300 to $500
annually to support the testing of glazes for lead. Currently, I am
in contact with the Tableware Education Enforcement Fund set up to
support Proposition 65. I have convinced them that studio potters are
a "non problem." That does not mean we should not be vigilelent.
Proper glaze formulation and firing are required. Use a
well-ventilated kiln. Marin Ceramics tested some copper carbonate and
found it had 60 parts of lead per million prior to firing.
If you want to contact me directly, I can give you more data.
