chemistry, alchemy, and blind luckPosted by Catherine Cartwright Jones on October 25, 2001 at 20:11:11: In reply to: Help from the Sirius Mixmasters, please posted by Lauren on October 25, 2001 at 19:33:50: At the moment you terp your paste, the molecular change starts. Everymoment from that, your henna will have more of the shallow-penetrating dark brown molecules and fewer of the deep penetrating orange molecules. Factors affecting this are heat, amount of terp, porosity of skin, perspiration, thickness of line, keratinization of skin, whether or not you waved a dead chicken over it and how fast butterflies were beating their wings in Madagascar. That is to say .... you can make an educated guess about what's going to happen, but alchemy and blind luck may blow your guess out of the water. As many experiments as I've done with the terps .... I suspect that the uncontrollable variables are as great, if not greater a factor than the controllable. The current fade-down of the "Oh my Lord Increase me in Knowledge" is interesting in that respect. I terped it about 24 hours prior to application (as I recall). In many sections I've been able to peal away the near black terped (oxidized Lawsone?) cells to see the underlayer of orange (regular Lawsone?) cells. The terped henna penetrated to a specific depth, and the unterped penetrated farther. I'm using the plain henna fingertip diamonds as a point of comparison. If you have a lower precentage of terps, or shorter terp-soak, you're apt (but not guranteed) to have a thinner top layer of darkdark color and more underlayment of dreamsicle orange.
