Seriously though, I am perpetually perplexed for this modern mania for
marking the margins.
I think it's a response to blunt knives. Alternatively, and going back
to a thread of a couple of weeks ago, a response to cutting tissue
before it is fixed and firm, AKA quick turnaround time, AKA keeping
ahead of the competition.
If you cut with a sharp knife when the tissue is fixed and firm, there
will be a flat embedding surface. The real edge of the tissue will be
the bit where tissue becomes empty space. Is this so difficult?
The suggestion of having buckets of silver nitrate around the place is a
species of insanity to my thoughts.

Poisonous. Causes burns. Long-term exposure can cause permanent
blue-grey staining of eyes, mouth, throat and skin, (argyria) and may
cause eye damage. Short contact can lead to deposition of black silver
stains on the skin. Very destructive of mucous membranes. Skin and eye
irritant. Experimental equivocal tumorigenic agent.
ORL-MUS LD50 50 mg kg-1
UNR-MAN LDLO 29 mg kg-1
ORL-RBT LDLO 800 mg kg-1
SCU-GPG LDLO 62 mg kg-1
IVN-RBT LDLO 9 mg kg-1
Would you really want a bucket of the stuff lying around for people to
dunk things into and increase the surface area for exposure?
I would suggest you carry out the procedure in a fume cupboard with
small quantities, wearing gloves and lab coat. Mind you blue-grey eyes,
mouth, throat and skin might be rather attractive.

I want it said of me by those who knew me best, that I always plucked a
thistle and planted a flower where I thought a flower would grow.
