Is there a easy way of determining whether or not gelatin has hardened?
Apparently, hardening is not an all or nothing affair. It hardens over
time, differently with different hardening agents and dilutions. And now
I'm reading that the ph is also a factor which I suppose means support
selection is also entered into the mix.
So, short of actually making a gum print and having it fail, is there some
kind of clue to look for that will indicate that gelatin has hardened
sufficiently? A chemical test perhaps?
