Re: Trichrome staining.

From:"J. A. Kiernan"

Tony raises an interesting point. I haven't been able
to find the original publication of iron-celestine
blue followed by haemalum, which has been popular
for many years in the English-speaking world outside
North America. There are plenty of published references
but all the ones I've seen cite secondary sources.

Even the superb 796-page fifth edition of "The 
Theory and Practice of Histological Techniques" 
(Bancroft & Gamble, 2002) gives a procedure with
no references or even speculation about how the
method works. There are plenty of old papers about
iron-celestine blue B alone as a nuclear stain. Why
is it advantageous to follow it up with a haemalum?
