Re: Most mordants are metallic salts.
Posted by Catherine Cartwright Jones on June 4, 2002 at 00:19:14:
metallic salts (such as "Glauber's Salts) that sort of "chew up" the
surface of the fiber a bit so dye has more sites for binding (thus
better color). That's why Mordants are called Mordants, from the
Latin word "to bite". Some henna kit company or book writer called
lemon a mordant for henna, and it's NOT ... but the error has been
repeated and repeated. (Some editor was sleeping on the job).
Also, henna is unlikely to stain commercially prepared cloth, as most
"ready to wear" fabrics have surface treatments that make them resist
dirt, brighten color, and resist wrinkling. Henna is only going to
stain "raw" fiber.
