I've smoked a great deal out of my corncob pipe and the taste is very nice, normal, and appealing. I've recently purchased a Mr. Brog #21 Old Army pipe. I packed the bowl and tried it out on the spot right after I received it. The taste still gives me shivers. It was something related to plastic burning or something just noxious. The bowl is of peachwood with a grey coating on the inside. Since I've not had this problem with a corncob, I can only blame the material. But I'm not sure. Any advice or help would be greatly appreciated regarding stopping the taste. Thanks
