The RV Project has posted two pictures illustrating the destruction of one of the most classic V7s in the country, Deception at LRC. This hits especially close to home because I just returned from a recent and brief trip to the fabulous boulder fields of the south east. A while back I wrote a post about the effects blowtorching can have on rock. A number of people commented that it can be done acceptably. Perhaps that argument could still be made, but I will continue to advocate against the use of blowtorches to dry wet rock. Photos like this demonstrate the potential effects on God’s stone.

Please do not blow torch wet rock!!!

    No proof the torch did it. Most likely this broke from fat andy climbing it after a rain.

    Blowtorching holds is a fools game. There is not an argument for it, or at least an argument that makes any sense.

    Rapid thermal expansion of a crystalline solid structure (dry or hydrous) introduces partitioned strain into the crystal lattice of the solid. The weakest link is where the strain partitioning occurs and is where failure is initiated. Even slight crystal lattice failures, those that can’t even be seen by the human eye are irreversible and accumulate over time. If a rock is heated enough to drive water out of it, it is undergoing these lattice failures!

    In every day terms, blowtorching is the same as hitting a hold with a hammer. Light blowtorching is like small taps, heavy blowtorching is the big swing and whack. Small taps add up and every one is non-reversible. “Responsible blowtorching” is time bomb and in the end is the same as just chipping the holds off of something.

    Don’t blow torch holds! There is no excuse what so ever and no argument at all for it.
