Well, following a discution with Erica in spring of summer this year. I claimed i could burn a barrel fast and burn the paint very well.
Here the first try of my rockwool technique. All the barrel was glowing red, to orange within 15 minutes And surprisingly it doesn't stink that much.

You would have heard the roar. It was mad! So mad i was laughing on my own.
