Today i post from the computer- a rarity for this blog. but i was sitting here with my coffee and looking over my google alerts and morning emails and saw something that made me want to write this post. i don’t think it is ready for the main blog but something i think those here and perhaps over on the indigo forum might find relevant. especially the indigo forum so i will post over there as well.
here is what i saw first.
and then this-
and wondering where people get this stuff from i found many such sites all repeating the same sort of jargon-from henna and indigo hair dyeing and more. what came first? the chicken or the egg? the science or the tweet?
as the “trend” of indigo winds its way through popular culture without any real understanding or reverence for knowledge of the ages it can be expected that this sort of thing will occur. and then the “new” knowledge can supplant the old. it can be tweeted, tumbled, posted, liked, shared, but what if the “new” knowledge is completely wrong?
“After being dip dyed- the shirts get rinsed, dried, rinsed again in a vinegar and salt solution (to prevent bleeding), washed, hung dry…”
so of course i know this is simply not true. but it might “ring true” to someone who knows nothing about dyeing indigo. or to a couple of surfers from the OC of NB who decide to dye some “natural” indigo (translation-they likely bought an indigo kit which uses synthesized indigo that has been pre-reduced) for their shop. of course they now have achieved expert status.
so just to clarify- vinegar or salt rinsing DOES NOT set indigo. i think we all know here that indigo is only soluble in a reduced state. insoluble in an oxidized state. the whole thing about vinegar rinsing comes from the fact that on certain fibers (silk and wool) rinsing in a mild acid solution restores the pH and the hand of the fiber (or hair!). it does nothing for cotton that a good rinsing won’t do. Japanese dyers tied their indigo to sticks along the rivers to washout. after many many dips in the indigo vats. for hundreds of years. perhaps we ought to ring them up and let them know that a couple of surfer dudes in OC have discovered THE ANSWER.
of course the new experts don’t back up their nonsense with any science- they simply state FACT! but if you are interested in a slightly more scientific explanation you can go HERE. and decide for yourself.
OK enough, so much to do. and the temp is rising here again. 90’s they say. oh boy!
