Ah, very interesting. Unless I've done something bad, like leaving coated
or undeveloped print long time in hot weather, I don't need to clear gum,
so would never have thought of that.
Was there any discussion about *keeping* working solution of glyoxal? I
recently used some kept about 3 weeks. Didn't harden the gelatin -- it
stained badly. Today I'm going to try some just 2 days old with some
methyl alcohol in it as preservative.
I wonder if it would keep better in refrigerator?
