Hey everyone. I'm not specifically "new" to pipe smoking, but I am new to new pipes. I was fortunate enough to inherit my grandfathers and fathers pipe collection after they passed (about 15 pipes). So I've always used those for the last few years. I have recently started building and adding to the collection with my preference types. My question is about the coating or lining that is put in the chamber of some pipes that is a dark color. Some pipes have a coating in the chamber and others are natural wood. Is the "break-in" period the same for both? And is there a different way to take care of either types before they build a cake?
