Hi Folks,    
In our gross room, (and maybe in most-I'm not familiar with the
    practise) our pathologists are using 1% silver nitrate to see
tumor
    margins in bowels, breast, etc. by pouring the solution onto the
tissue
    prior to slicing.  One pathologist has suggested keeping a bucket
of 1% 
    AgNO3 in the gross room so that the tissue could instead be
briefly
    immersed.  I know that if we use a plastic bucket the plastic will
be
    forever stained which is of course no big deal, but will the
plastic
    compromise the shelf life of the solution itself? 
    Thanks for your time.
    Greg
