text: In natural dyeing, there are 'fast' dye compounds (those that have the necessary molecular structure to form stable chemical bonds with mordants and fibres, and so provide good resistance to fading when washed, exposed to light, or subjected to normal rubbing/abrasion; these are found throughout the historic record), and there are 'fugitive' compounds, which are not true dyes (those that fade and wash out quickly, as they lack the molecular structure to form stable bonds, or any bonds at all, to mordants and fibres).
