Hey guys, I ave a few mason jars around my house. I hear a lot that mason jars are one of the best methods to storing your tobacco, but wouldn't heating the jar with tobacco in it ruin the tobacco? That's the only method I know of sealing a mason jar, putting both pieces in boling water and closing the jar and letting it cool down. May any of you tell me if this is safe to do or if there's another method of closing it? Thanks.
