acrystalline piece of rock and therefore much more sensitive to temperaturechanges than granite.
Can you not understand though, that if someone who doesn't know any better see it in his video, or indeed yours now free to view on vimeo, they might deem it an acceptable practice and do it on their own local rocks?
I still see your point regarding the influence the video might have upon others.
Some rocks are more sensitive to this than others. You've clearly proved from your video that you shouldn't blow torch this type of rock. You've also proved that you are unqualified to identify different types of rock and therefore make a 'judgement' on whether or not it could take such a rapid temperature change. Therefore, this should be frowned upon across the climbing community and should not be publicised in videos by people of influence.
Webb has responded to a comment on 8a - not used on the rock at all, but for drying shoes apparently.
