RE: AEC
Dear Sylvia,
The problem of fading AEC reaction product sounds familiar to me. For some
unknown reason I have some still beautiful red sections here stained in the
mid 80-ies. However, all sections stained later start to fade after half a
year. I still think that we have had a very special batch of AEC in the mid
80-ies, that isn't produced ever again. For the best you protect your
AEC-stained sections from direct (sun)light. The real precious ones (such
as my course slides...) can be successfully stored at -20C.
