ABSTRACT:
A glass article cutting method by which a glass article can be cut not only along a linear line but also along a curved line of a desired profile and can be cut comparatively readily even if the glass article has a concave or convex portion on a face thereof or even if the glass article has a complicated three-dimensional profile. A conductive coating material such as colloidal carbon is applied in a linear line or a curved line on a surface of a glass article to be cut, and a high voltage is applied from a pair of positive and negative electrodes to the line of the conductive coating material to energize the conductive coating material to generate heat thereby to cut the glass article by thermal stress caused by the heat.
