Note that eye shadow may not be archival; it may have emollients or other ingredients added to make it safe for skin, or filler to stretch that dollar-store budget pricing. If you're just fooling around & having fun with color it's a great option, though. :-)
I thought the same thing but, I have bought many of the eye shadows from dollar tree to make these paints and the only ingredient, that the label states, is mica. There are absolutely no other ingredients mentioned.
Your video is WONDERFUL. However, I am sorry, I really really really hate this song SO passionately, I just can't help it. So I muted it and played Roxy Music's Avalon instead. Start it up about 20 seconds in and oh, goodness, it's magical.
