glaze disposal

Hi all;

I have 2 kg of earthware tin glaze (low sol) I no longer need and I want to
get rid of it so that I can re-use the bucket.

I found in the archive that the best way is to fire it so that it's solid
and I can dump it, rather than putting it down the drain.

I am not sure exactly how to do it. Like what's the maximum amount I can put
in a bisqued bowl?

I don't fire to eartheware temp anymore, perhaps I can put it thru bisque
firing at 1000 C? There's lead frit in it, surely it'd melt at a low-ish
temperature.

T.I.A.

Put it in an old paint can and take it to the toxic disposal site nearest
you. Just tell em it's old lead paint you found in the garage.

Why not just add it all together and make a scrap glaze out of it? It
might look good with a little this or that, then use it as a liner in
pots where the inside color is not critical. Mike Gordon
