wanted: unstable glazes

Hello everyone,

I'd like to get some recipes of glazes that look great, but turn out to
be really unstable--like ones that won't stand up to a day or two soak in
vinegar without losing color.

Yes, I know my focus has been on how to make glazes stable, but as part
of that I need to fill in the domain of unstable glazes.

Since these aren't glazes that we really want people to use on functional
work, please send them to me privately at and
don't get them in the archives by posting them to the list.

Any cone, any atmosphere is Ok--just tell me what it is. If you know the
original name or source I'd appreciate that too.

Thanks, John
