Abstract

Process for treating glass sheets with a relatively acute angle of curvature, characterized in that it comprises a band of coloring agent applied to a surface of at least the sheet and along the line around which it is desired to bend the sheet. Sheet, superimposing a conductive path of electricity on this band and longitudinally to it, and applying an electric potential along said path, of a sufficient magnitude and for a suitable time to heat the sheet in the area immediately adjacent to the path until a temperature higher than the curving temperature of the glass and causing the sheet to bend or curve along the line and forming a spot of pleasant or desired appearance along the line.
