lead in my kiln

updated mon 23 feb 98

 

Ron & Dianna Phillips on fri 20 feb 98

I bought a kiln, and at the suggestion some of the Clayarters, I bought a
lead test kit. I was sorry to find out but glad to know that the nice lady
I bought it from had indeed fired lead in it. The lid tested negative, but
the shelves, floor and lower walls were pink-for-positive.

Any advice?

I thought of having the bricks lightly sandblasted and then coating
everything with ITC to try to trap the lead under the coating.

Any comments?

If I don't get any advise or comments, I guess I'll just have one last
question -- how do I dispose of the thing without getting in EPA trouble or
passing my problem to someone else?

Ron:
The lead in your bricks will soon dissapate with use. In the meantime there
will b e lead release with each subsequent firing. If you really want an
expert opinion I suggest that you contact Monona Rosoll here on Clay Art. You
can count on her for the most accurate information.

Ron,

I certainly wouldn't tell you what to do but if it were my kiln I would
run it very hot, empty and exhaust the volume many times during the
backout to the outdoors. The problem is not really the lead but
ingesting or breathing the vapor. Keep baking and exhausting until the
shelves, sides, etc test negative. Than a coat of ITC would finish the
job and be a good preventative.
