Yesterday I went to a thrift store and bought a no name pipe that has rustication on it for 12 bucks. I did a salt and alcohol treartment and reamed it but I noticed a very small hole about the size of a needle head right where the bowl meets the shank. I placed my hand over the top of the bowl and took a puff to see if the hole was clear through and sure enough, it was since it whistled and I could feel a stream of air... It seems to me that it had a filling in there but maybe it fell out. This can't be good for the pipe if I tried to smoke it. I really like this pipe and I was wanting to know if anyone knows of some kind of compound I could use to fill this in that would last forever.
