What is that black ...whatever that is, in the bottom of my vaporizer?

I know, I know...'minerals from the water' but that really doesn't tell me much. I can boil water in a pot until it's dry, and never get that black pellet to form. What is it, and is it caused by some process that occurs in the heater core-thingy? (Yes, 'thingy' shows you my scientific expertise).

    This is black and feels oily when you try to wash out the vaporizer.

    It may be copper oxide from heater coil or chemicals like salts and dirt from water.

    Normally i find such salts as white.
