Leathertongue and tongue burn are the same thing. The reason we need to define the difference between the two is that I get a number of calls and emails asking for help with these problems, and if I can't determine what the source of the difficulty is, I can't properly advise people how to deal with it. I can tell you that, going back to the seventies, the difference between the two was generally understood, but back then, you were more likely to know a number of pipe smokers who could clarify things.
