WHOOPS--talk about typos--I mean "how to harden gelatin". And one more
thing, surface is still gritty with glyoxal and the lower 15 ml dilution
bath, I forgot to add that point, but MAYBE Katharine is onto something that
the amount of glyoxal, 15 or 25 ml, produces crystalline hardening...perhaps
even less would produce less grit, or perhaps it always crystallizes gelatin
no matter what amount.

All this talk almost makes me want to size another batch with
glyoxal....never mind....
