Another bowl of Three Nuns. This time in a massive Mastro Beraldi bent Dublin. It's a beautiful pipe with flame grain and a ton of birdseye on the wide rim, but there's a spot about halfway down the side of the bowl that gets hot very quickly. All I can think of is that there's a large fill on the inside of the bowl that I can't see. The pipe came new with a carbon coating in the bowl, so I couldn't see any imperfections there, and the outside is flawless. Never had a pipe with this problem before.
