    Does it really matter which black I use?

    At the behest of some suggestions I got on my crap art, I'm going to go out and buy some oil paints next weekend. It was suggested that I go get some titanium white and some ivory black. The problem is that I looked up what ivory black actually is and it turns out it's bone char. Since I'm a vegetarian, I'm opposed to buying this, so my question is is there a vegetarian alternative that is just as black as ivory black? Does it really matter which pigment I use?

    Show me a sane man and I will cure him for you.

    Point 1: Modern Ivory black is almost certainly a synthetic. Real Ivory black made from bone carbon is almost expensive as lapis lazuli in today's market.

    Point 2: Mars black is better than Ivory black, and it's an iron oxide. Hope you're allowed to eat metals...

    Point 3: The other blacks available are made from furnace scrapings, burnt screaming vegetable materials, and a lot of generally poisonous petro-chemical shit and are not as good as Mars Black.

    While I admire your dedication to your beliefs and would never make fun of you for them (and I mean this most seriously), I DO find it interesting that all of the replacements that allow you to specifically forego animal products are incredibly poisonous for an extended time to all life on earth.

    That being said, I would suggest that you google a bit or check your local library to verify the actual components of modern paints before you jump to conclusions based on possibly out-dated information. You may find less of a problem than you thought when looking for animal-safe products in the art world. They even make paper out of elephant shit, as well as bamboo-bristled brushes, and most modern pigments are not made from animal parts due to fugitive paints being replaced with non-fugitive "modern" chemicals that just kill everything equally.

    I hope this doesn't come across as sarcastic or patronizing. It is not meant that way...

    Of the manufacturers sites I could see they list their ivory black as being PBk9 (= bone black) . Made from charred animal (presumanly cow or something similar) bones. One web site I checked had it selling for approx $18 a pound for the pigment.

    Found on a paintmaking site I just found thru google...

    "Ivory Black PBk 9 ASTM l
    Also called Bone Black
    Chemical type and description
    Inorganic synthetic carbon black and Calcium Phosphate. Bone Black was invented by the Romans as a general purpose black and for the best grades pure ivory was burned instead of ordinary animal bones. Thus it started with 2 separate names. True Ivory Black has a higher carbon content than Bone Black and is more intense. It is the deep velvety black found in the backgrounds of Rembrandt's portraits. It wasn't until the 19th century that artists allowed the application of the name to the ordinary Bone Black. The genuine pigment is still made in tiny quantities from Ivory harvested from animals that have died naturally but is almost as expensive as genuine Lapis Lazuli Ultramarine. These comments apply to both forms of Bone and Ivory Black. A very slow drier in oil, it should never be used in underpainting. It produces a soft and brittle oil paint.. It can never be used in Fresco as it effloresces. It is the work horse black for artists and until the development of Mars Black was the best black artists had for oil paint .
    Toxicity
    Is considered toxic. Do not breath dust.
    Media suitability
    Linseed oil, Alkyd, Acrylic, Tempera, Encaustic, Pastel, Chalk"

    I think this pretty much supports what I said. Wish I'd seen this before I posted...

    It kinda did, but I'm used to the internets, so I don't much care. It's hard being a treehugger in this modern age. I'm all about saving energy and recycling and whatnot, but at the same time I'm a computer science major who practically never turns her computer(s) off. D:

    So Mars Black will work better? Basically all I'm doing is getting some oil paints to do some value studies. I've never used oils before, so the thought of getting a bunch of toxic chemicals is unsavoury enough; getting something with animal parts in it is like adding insult to injury, I guess. Even if it's not bone char (which it wouldn't surprise me if it is, given its extensive usage in sugar production) and is just some horrible inorganic compound, an iron oxide seems a lot more environmentally friendly.

    Interesting that paints, what seems to be rather ordinary items, are made from such exotic materials.

    If you're just using black and white, then no, it doesn't particularly matter. Mars black will be fine. Different blacks, like different whites, have different handling, drying, and mixing qualities. Here's the rundown:
    Ivory black- Called that because it was originally made from charred ivory scraps. Now made from charred animal bones. Carbon with some calcium phosphate and other trace materials. Slow drier, good mixer, the deepest and most transparent black. For those without animal product issues, the best all-around black pigment.
    Lamp black- Pure amorphous carbon from burning natural gas. Extremely slow drier, gives lovely bluish grays with white, but can be sooty and overpowering in mixes.
    Mars black- black iron oxide. Average drier, good tinting strength, dense and opaque. Not as deep a black as ivory, warm top tone, cool undertone.

    So if I used Titanium white and raw sienna, a good 3rd color to use would be Ivory Black or Mars Black?
    Now if I had to make a decission between the two?

    It is interesting. A book I’m currently reading called "What Painting Is" by James Elkins compares oil painting to alchemy and has many educational revelations about the pigments we use. Painting is usually just smearing mud on a canvas (very pure, brightly coloured mud mind you), but sometimes the processes that were required to create paint were quite exotic.

    For example "Early in this century a gelatinous extract from the swim bladder of sturgeons was used as an ingredient in oil paint." To make Vermillion "In the Dutch technique, mercury and melted sulfur were mashed together to make a black clotted substance called Ethiops mineral or Moor. When the Moor was put in an oven and heated it gave off vapour that condensed onto the surface of clay tablets. The Moor is black, but its condensed vapour is bright red - a typical piece of alchemical magic - and it could be scraped off and ground into Vermilion for paint."

    and

    "Painters' media have included dozens of European and Asian plants, oils made of spices like rosemary and cloves, and even ground up fossilized amber. ... Rubens and his contemporaries boiled oil and lead into a stinking mixture called black oil, which was stored in airtight containers. To extract the particles of blue lapis lazuli from the colourless rock surrounding it, painters used the 'pastille process'; they pulverized ore samples in a bag, mixed them with melted wax, plant resins, and various oils, and then kneaded the bag under a solution of lye (made with wood ashes) to coax out the blue particles."

    "Lead White, the best white paint before the nineteenth century, was made by putting cast 'buckles' of lead clay in pots partly filled with vinegar; the pots were stacked in a shed with fermenting horse manure or waste tanning bark. Every few weeks the painter's assistant would scrape the leprous flakes of lead carbonate off the buckles and put them back for more steeping."

    I just find it fascinating – although now we just go down to the art store, everything’s in tubes – All we need to do is make sure not to mix acrylic with oils and always paint fat over lean.

    I personally don't use black at all.

    This reminds me though, anyone know where I can get my hands on some Mummy?

    Tristan, I can't figure out how that works. Are you saying it's warm when it's a lightened with a higher value color... and then cooler when mixed with a darker value color?

    I think it's warm when used in glaze and cool when mixed with white.
