Carsons Mordant 
. substance’s or metals that act as a link between dye and tissue 
 
A mordant is a metal with a valency of at least two. The two commonest metals used in histotechnology are aluminum and ferric iron, both with valencies of three. The attachment of mordant to dyes is by means of a covalent and a coordinate bond.
