Ok so I know this has been on before, but this is the first time in a long while that this has happened. So I was smokeing some AF Watermelon with two quarter pieces of exotica coals on HD foil on my vortex bowl. The shisha was sprinkled in to just below the holes. The smoke was hot and the bowl didn't last long before it started to burn. Now to me I think it was to much heat and or not enough shisha for the amount of heat that I had. Just wanted to see if you folks are thinking the same thing. Thanks.
