I watched the SGA season finale
Mar. 8th, 2008 05:40 pm( spoilers for SGA 4x20 )
Totally unrelated to SGA I learned a new piece of trivia today: I've always been vaguely puzzled by the color name "ivory black" because it seemed contradictory (ivory not being black and all). Then today I happened to look at the label on the back of a tube of acrylic ivory black, one that went into all kinds of technical detail that I have no idea what it means (it has some kind of numbers for hue, value, chroma and codes for the pigments and symbols for opaqueness and lightfastness and so on) but also had a list of ingredients and apparently that black is made from charred animal bones. Hence the name "ivory black".
And I get that historically, though I'd have thought that by now the color would be synthetic. I mean, it's not they are still grinding up lapis lazuli for ultramarine (well, I guess there might be people who are into restoration and such and make their colors themselves from scratch with pigments or specialty producers who still do that, but usually it's synthetic these days). So it's kind of gross that they still use animal bones, but that what the tube says in its ingredient list under the "vehicle: acrylic polymer emulsion" there's "pigment: amorphous carbon produced by charring animal bones". So I'm using the same pigment as my prehistoric ancestors, I guess, only in a prepared polymer solution rather than charring some hunted mammoth's bone myself. Still in my mind "gross" kind of wins out over "artistic connection across millennia of history".
