Abstract
The edge portion of a plate glass is locally heated to a temperature higher than that in the other portion of the plate glass, after the whole of the plate glass is heated. Electric current is thereafter applied to the edge portion of the plate glass in order to further heat the edge portion so that the edge of the plate glass is slightly melted.
