PROCESS FOR TREATING A GLASS SHEET ADAPTED TO BE BENT TO A RELATIVELY SHARP ANGLE

摘要

A process for altering the residual stain remaining along the relatively sharp bend of a glass sheet resulting from the fusion of an electrically conducting glass frit suspension applied to the sheet along a path coincident with the line about which it is desired to sharply bend the sheet by passing electrical current therethrough to heat the glass adjacent thereto and effect the bend. The process includes interposing a strip of coloring agent between the glass sheet surface and the electrically conducting path lenthwise of the latter prior to electrically charging the same to form a resultant stain along the sharp bend of desired appearance. ,
