Mordant literally means "to bite". The mordant is the chemical link that fixes the dye to a substrate by combining with the dye pigment to form an insoluble compound.
Most natural dyes need a mordant to fix the color to the fiber and increase lightfastness. Some common examples of dyes that require a mordant are cochineal, madder, fustic, osage, and logwood.
Made from Aluminum Sulfate.
