This is reminiscent of urban legends I've read or heard, so you might want to check out some urban legends sources. Incidentally, there was some red coloring that was discovered when animal bones were added to a mixture, but my college sculpture professor told us that the legend was that it was discovered when an unsuccessful artist committed suicide via kiln.
