glaze testing rejects

With all the discussions lately on the toxic nature of glaze ingredients in
dry and wet form, I'd like to know what you do with all those test sample
glaze batches that are rejects.

At one time, I use to dump all rejects into a "everyman's" container
thinking that I could at least use it for lining, but after seeing what it
look like I stopped using this mix.

And what about those buchets of glaze that you no longer know you're not
going to use? Dig a hole in your backyard and dump it in? Let it evaporate
and sent the contents in the plastic bag to the dump? What?

Sorry, if this has been discussed before, but I hope since then there may
be other alternatives.

The best solution I've heard is to throw and bisque fire as many large
bowls as it will take to accomodate the glaze. Poir the glaze into the
bowls and fire it to whatever temp. is appropriate for your glazes. You
will now have a bowl with a lump of glass in it that has been rendered
insoluble and may be safetly disposed of.

Regards,

Greg

I add all the left-over tests and rejects to my claybody
the next time I mix clay.
A little extra flux.
I add about 2 cups per hundred pounds of clay and it's
not the least bit noticeable, in workability, fired characteristics,
or color, even an iron saturate glaze in white stoneware.
