We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Check the "Dirty Jobs" show on Discovery and search for Bone Black. It is a fine powder made from burning bones to charcoal that is used in paints, baby powder and others items. Stands to reason that it could have been one of early human's first chemical additives.
Second thought: Had a friend once that ran a cemetery company. If the ashes from a cremation weren't claimed (happened all the time) the guys would scatter them among the rose bushes because they contained bone meal. There was a problem sometimes when denser bone ends wouldn't burn completely and could be found under the flowers. Kind of put the customers off.
