I just got this pipe on ebay, and noticed that this pipe has been patched and it looks to go all the way into the bowl. Thankfully the pipes I bought were not expensive, but the seller did not mention this and I wrote to ask him about it. He actually cleaned these pipes and made them look nice or so he said in his sale listing, so he had to see the spot it isn't the same color as the other parts of the bowl. I was wondering about pipe putty or other materals. Anybody use it? Anybody smoke a pipe that has been filled like this? I'm not too keen on the idea of smoking something out of this pipe not knowing what was used and if this stuff is going to affect the taste of the smoke, or lace it with something unhealthy. Thoughts? Here are a couple of pics of what I'm talking about.
