   A simpler method, with not so many things to vary, should
   be the answer.  Picro-sirius red is an excellent collagen
   stain that works pretty well every time. It's an improvement
   on van Gieson, and will show very thin collagen fibres. The
   sensitivity is greatly enhanced if you have  polarizing optics
   on your microscope.  The method is in several textbooks.  If
   your library is lousy (so many are!), just ask again and I'll
   send you the detailed instructions.
