We take a hairdryer and dry the inked tissue until it gets a shiny surface.

Betreff: [Histonet] Speaking of margins...
We use different inks and marking dyes for our margins.
We have stopped using bouin's as a mordant to keep the ink on the
tissue through processing, and switched over to an acetic acid
formulation. Could anyone please share what they use to help keep the
ink in place? Bouin's is hands down better but quite stinkish.
~ I had suggested to the residents and PAs that are grossing to perhaps
lighten up on the administration of ink....any backers on this?
Have a great weekend!

In my travels to a large number of surgical pathology services back to
1965, I have never seen silver nitrate (AgNO3) used to mark margins,
though I've seen references to it in the literature. It seems to me
that its environmental problems (and the expense) make it a poor
choice. If your pathologists want a tub of something to mark whole
specimens with, I suggest india ink (bought cheaply from an art supply
store) or black marking ink (bought expensively from the folks that
keep the cost of medical care high). I've seen india ink handled this
way in a number of labs, though my personal preference is to swab the
