Hello, Just smoked my Markus Fohr #20 clay for the first time. It smokes wonderfully. Very cool and dry. My first intimation that the tobacco had all been smoked was when I drew and got a bit of powdery ash in my mouth. I dumped the pipe and it was clean with no residue or dottle. I ran a pipe cleaner through the stem, and it came out still white. I’m very satisfied with this pipe. Thanks again. Matt H.
