If there were any markings, they are long gone now. I thought that at first too, but there's a couple of hitches, it can't hold water, unless it use to be welded together, and there's no way of getting a candle in that bottom part as far as I can tell, and it has holes in the bottom of the chimney like something is suppose to burn down there. Could it be a version of a hookah, or something like that?
