What about getting the burn out around the lip of the bowl or on the bottom. I dont want to take away the wood thats there just the black thats blead through the wood?
If the briar has blackened from the heat it may not come out completely. If it's just crud on the rim,spit and a rag will take it off. But if the wood has blackened from heat,gotten almost hot enough to char,then it's there to stay most likely. You might sand some of it out. Even the dark spot at the bottom may not sand out completely. Some pipe develop "hot spots" in the briar,usually at a thin area that causes the wood to turn black and there is no removing it-- usually.
Oh,guys,watch that Ozark Southpaw guy--he's nuts!
