Sheehan states" Calcium oxalate will not color with hematoxylin or alizarin 
red.  Oxalate salts are considered to give usually a negative von Kossa 
reaction, but there is disagreement concerning this characteristic."  She 
gives Pizzolato's method for calcium oxalate.  If you do not have a copy of 
Sheehan available, the reference (which you might like to read) is 
Pizzolato,P: Histochemical recognition of calcium oxalate. J Histochem 
Cytochem 12:333-336, 1964.

Hope this helps.
