Hi,
First I want to thank all who help me with undecal bone procedures.  Special 
thank to Diane from Cleveland, Ohio.
I use formic acid with sodium formate or sodium citrate for decalcification 
of bone in the laboratory.  This procedure is excellent and I have not 
problem staining with Mayer's hematoxylin.  My new boss want to use HCL or 
Nitric acid to decal large bone specimen because formic acid is too slow.  I 
need procedure for using these strong acids and how do you monitor the end 
result.  I will using this method to decal mandible etc.  Thank again for any 
help that is given.
