mordants
Color-locking chemicals
Mordants are substances used in dyeing to fix colors to fabrics, making dyes permanent by bonding them to fibers.
Common mordants include alum, iron, and tannins.
The term extends to any agent that fixes or sets something in place.
In etching, a mordant is the acid that bites into metal plates.
The singular mordant also means sharply critical or caustic: mordant wit, mordant humor.
