Although some materials, e.g., silk and wool, can be colored simply by being dipped in the dye (the dyes so used are consequently called direct dyes), others, including cotton, commonly require the use of a mordant (see also lake). Alizarin is a mordant dye and the color it gives depends upon the mordant used.
