    According to Wiki
    Cremated remains are mostly dry calcium phosphates with some minor minerals, such as salts of sodium and potassium. Sulfur and most carbon is driven off as oxidized gases during the process, although a relatively small amount of carbon as carbonate may remain.
    Is this suitable for carbon processes?

    Both. But it was a very dark image, tonally. I'd have to ask her but thinking on it, I suspect there was a good bit of black pigment mixed in.

    A little more on the subject of burning bodies -

    It seems that cremation takes place at higher temperatures than those which are used for the production of "bone black" or "bone char" - the carbon is cooked off whereas lower temperature and less oxygen yields the dark pigments we know as bone, ivory, vine - black.
    I'm not sure if one can request lower temperature and oxygen deprived cremation (who knows.. possible business opportunity? UGH).

    What about DIY cremation? Oven cleaning cycle?

    I suppose I wouldn't be against mixing in some pigment with my ashes.

    Maybe there's a market for the cryogenics people.... they could save a lot of money by just being content with eternity in a portrait.

    That would require the Portrait of Dorian Gray to make the cryogenics folks happy.
