This latest time round I used Chronic Hookah instant light coals. The pipe is a Mya QT and the hose is a standard Mya. It's all clean and airtight. There aren't any funky smells. About burning, how can I tell if that's happening? When I peeled the foil off the bowl, a layer of shisha stuck to the underside and I got a smell of burnt food. If I did burn the shisha, how do I avoid doing so later?
About these CH coals, they don't instant-light very easily. I held one over my pipe lighter until the latter got too hot to handle. Then I went to the stove and they very quickly started sizzling like I expected. I suppose a torch lighter would make things easier, but I don't have one.
