mordanting

This term is highly specialized, used almost exclusively within the contexts of textile arts, chemistry, and historical dyeing practices. It describes a technical preparation phase rather than the act of coloring itself, focusing on the chemical bond between the fiber and the pigment.

As a noun, it refers to the overall process or the specific state of being treated. When used as a verb, it describes the active application of a mordant, such as alum or iron, to prepare the substrate. It is rarely encountered in general conversation and is typically reserved for instructional manuals or academic discussions on material science.
