I can't seem to get a good picture of it, but I have a glittery substance in the chamber of an unsmoked pipe. Can crystals form on briarwood? It's an unsmoked Savinelli Orient 644 KS that has been sitting it's pouch and box for at least two or three years since I've purchased it. I was having a discussion about non-black stems and it make me think of the pipe (I forgot that I had it). When I pulled it out, I noticed the chamber sparkled when introduced to bright light. It is not noticable unless bright light is shined in the chamber. Has anyone else experienced this?
