Abstract (en)

A flame treatment for ornamental granite (1) slabs employs a burner (5) flame for local surface heating. The surrounding surface is maintained in a cool stress-free condition by a surface film of water (13) The burner flame is directed at the stone surface from which it is separated by a short distance. The water is kept away from the flame by air jets (19).
