A corner of my Temple Bar has this forming on a corner. Last time I sliced it off and smoked it anyway - don't know if I took years off my life or not. But what is it? Is it mold? I can rub some of it off with my finger. No strange "rotten" smell or anything like that. Just keeping it in a small mason jar in a dark file cabinet. If it is mold - what can I do? I had read somewhere someone suggesting putting it in the freezer. I don't want to keep slicing off to have it come back. And I can't really send it back to C&D from Canada - would be way too complicated.
