Awesome christmas present indeed
I don't really like mya bowls either, as you said they're kind of shallow. But i always pack my friends just really low, maybe 1/8-1/4 inch below the top of the bowl where the foil would be just go make absolutely sure it doesn't burn. It doesn't seem like much tobacco is in it, but i think the whole area of the bowl, like the diameter of it is a little bit bigger than my standard clay egyptian bowl so it winds up working out pretty nicely. You may have to move the coals around so all the tobacco burns evenly, depending on what kind of coals you use.
