"Bisepoxides are another class of excellent hardening agent. You can
buy this in a bottle and you can mix them in gelatin solution
as-is."
I spent a few minutes on google with no hint of a source. If you have
one, I'd appreciate it--I live in an urban area with no chance of mixing
outside and have asthma which precludes the volatile ones hardners.
Thanks
