    Based on all of the anecdotal evidence I've been able to gather
    along with some scientific investigation, I would say that what the
    Mexicans are doing is taking cans of automotive paint, mixing it with
    calcium and silicates (makes the stuff seem like something from the
    ground) and paraffin to add translucency, and laying it down either
    in distinct layers or swirled via the Jackson Pollock technique. Then
    they wait for the stuff to harden thoroughly (baking will certainly
    help) and then "mine" it and sell it off to cutters. Sound like a
    reasonable analysis?
