We used to have 5 litre flasks of haematoxylin ripening in the window for
months; if you got taken short you had to artificially ripen using an
oxidising agent. If you had enough stock then the sun did the work.
I always thought "organic" haematoxylin stained better that the factory made
stuff but I do think it overoxidised at a slower rate and gave 'cleaner;

Yes, Gayle's memory is still going strong! I remember
the boat rumor around 1976. And yes, I too was making
Harris hematoxylin with mercuric oxide "red". We
would let it ripen in the dark for a few weeks before
using it. What a wonderful sheen it had. I remember
a student was making it in the old Providence Hall
nursing school before we moved to our new lab. The
student added the total amount of the mercuric oxide
and it shot straight up to the ceiling and permanently
stained it. That was a heck of a lesson!
