Re: Masson's Trichrome (heating of Bouin's fixative in microwave)

Fear not the dreaded picric acid in Bouin's.  The ONLY 
way it will explode on you is if you first overboil it, 
getting it splattered over the inside of the microwave, 
THEN, let it dry thoroughly, THEN, hit a sizeable spot 
of the dried residue with a fairly large hammer.  You 
will get more of a "Phut" than a "Bang", if anything 
happens at all.
