I wasn’t trying to imply that these coatings are always a bad thing, if everyone read my post.
The problem for me as I mentioned is that I smoked half of a bowl and then let the pipe sit over night.
So the following day, it was like all the left over ash, tabac, and the coating turned into hardened crazy glue in the chamber, that was the problem.
So all I’m saying, with these coating, I wouldn’t smoke half a bowl on your first bowl, and then leave it over night, and expect the next day to easily wipe it out.
For me it looked like I had smoked the pipe a year and it already needed to be reamed out.
But since I sanded it out, a thin carbon build is slowly appearing inside the chamber nicely.
