Hello Derrick, this is the only one I have smoked enough to get some color out of lol. Anyway here is a couple of pictures that I just took one of each side of the pipe.
In this picture there is a mark where the wax was scraped off and has colored there. Also looking at the Pictures I can't see with my eyes but are some hair looking things I don't even know what that could be but will have to check it out. It isn't cracks must be some fibers inbeded in the wax from a pipe cleaner cause it isn't on the surface.
James.
