Look at the inside of the pipe when you first get it. Does it look black on the inside, or is it bare wood? If the bowl appears black once you get it, it is probably "pre carbed" which means it is treated with a substance that will help it break in naturally. If you see bare wood, it is not pre carbed, and it is a good idea to break it in in order to get it smoking at its full potential. A pipe that has a nice carbon "cake" on it will help insulate the bowl from excess heat and make your smoke cooler. You can ask 100 different people how to do this and get 100 different answers, but here's what I do: Get yourself a nice, neutral Burley blend, something like MacBaren Golden Extra, Butternut Burley, Storm Front, or even Carter Hall works great. Load the pipe to the top and smoke it as far down as you can. Smoke slowly and make sure the bowl does not get too hot because this can damage your pipe. When you are all done smoking, break apart the ashes and the dottle left at the bottom of the bowl, then put your hand over the top of the bowl once it has completely gone out, and give the pipe a gentle shake. This will coat the inside of the bowl with the ashes and will help build up a cake. Let your pipe rest for at least a day before you smoke it again, and keep doing this until your bowl has broken in properly. Hope this helps!
