I don't know if you ever seen what happens to rock or concrete when it gets heated with a flame, but I can tell you that it isn't pretty.

The rock can and will explode sending chunks in every direction. The more pouris and damp the rock, the bigger the bang.

Nothing good will come out of doing this.

Sorry Kabong, but someone gave you bad advise on this one.
