Barbara,
An alternate scenario might be for you to give it to
someone who uses lead/nasty glazes too. You could include
your wishes for it to be passed on and/or disposed of properly.
A warning about it's history could be permanently affixed on the
stainless sheathing with an engraving tool.

Dear Ron,
Thank you very much for your posting. As I read it (see below) my immediate
thought was of course that makes sense, I never considered that aspect. I'm
glad you did. Now it presents a different but more universal quandry.
On one hand, the hand of the individual, me, since I will only do about 4
firings a year in a lightly packed kiln with this glaze, and I never fire
functional ware, and I don't fire other people's functional ware it seems
that it is okay for me to use it. (already acknowleging that I take all
necessary precautions when using it)
But on the other hand, when considering what happens to the next person who
might own this kiln and fire functional pots, unaware that the kiln could be
imbedded with unseen toxic lead metals, a different obligation comes into
play. Although I would never sell or give away this kiln, what would happen
if I have no control over its disposal...like if I die first? Since I
ain't young, I would think that if I add a clause to my will to the effect
that this kiln cannot be sold or donated to any one and must be torn apart
and disposed of with toxic waste, that such action would fulfill my
responsibility and obligation to society and the future. What do you think?

Dear Barbara,
Just incase - as I do not see it mentioned here - a word about lead and
your kiln.
The lead will fume while being fired - particularly when it is reduced. It
reduces quite easily and becomes lead metal. There can easily be enough
reduction in any oxidation kiln to make this happen - and the closer to cone
6 you go the more likely it is to happen.
The end result is the lead condences out on the insides of the kiln -
enough over time to contaminate any ware fired in that kiln - just so you
know about that in case you or someone else decides to fire some functional
work in that kiln.
