Thanks to all of you who responded to my query about formalin detection.
The PAS idea is great.  Showed it to the pathologist, he was very impressed.
For those of you who answered to  simply label the containers, they ARE
labelled.  He just doesn't always believe that what the label says is what
is in the container!  What can ya do!? Just go along.
