Hello

I need an image or picture of the blue black stain of Weigert for fibrin.  I
have tried several sites from the net to no avail.   I am trying to stain
fibrin by Weigert stain for fibrin.  The one book i found that have the
procedure states that for differentiation 1 part aniline oil with 1 part
xylene.  I have tried different timing of differentiation starting from 2
seconds up to 1 min, however the blue black stain was not shown.  The
section is a thrombus

Thank you
