Abstract
A damage-free score, e.g., a subsurface score, in a moving refractory piece, e.g., glass, is initiated by imparting vibrations to a damage-free scoring wheel. The damage-free score is increased in depth by the continual impartation of the vibrations during the damage-free scoring of the piece.
