Thats a great point, never thought of that.
@Shit Snacks, I figure that a silicone tip like the gh or one of those disposable e cig tips would reduce the chance of getting burnt.
Also, is the bowl glass? I thought it was made of stainless steel.
Another option might be a glass/metal hybrid, sort of like this?
I'm not sure how feasible this would be, but the glass would diffuse enough heat to neglect any problems in regards to expanding/breaking the bowl, while still sturdy enough to not really worry about breaking.
