About to finish off a bowl of Presbyterian Match in a bent Apple cob w/ blue/white swirl spear style Forever Stem. I have been trying to prevent rim char on the cob and doing well at it, but it is still seeming unavoidable. (It is kind of still soaking in from the sides). Maybe if smoking half bowls... maybe. It's just not working even though I have done well at keeping it clean. It was a good trial.
