Abstract 1. A METHOD OF STRENGTHENING AT LEAST A PORTION OF AN EDGEE OF AN ARTICLE OF GLASS COMPRISING THE STEPS OF: ABRADING THE SURFACE OF AT LEAST A PORTION OF AN EDGE OF SAID ARTICLE OF GLASS FOR SMOOTHENING SAID SURFACE; AND, AFTER SAID STEP OF ABRADING, (A9 SUBJECTING THE SMOOTHENED SURFACE OF THE EDGE TO A RECTIFYING TREATMENT WHICH INCLUDES THE CONTACTING OF AT LEAST THE SMOOTHENED PORTION OFF SAID EDGE WITH A MEDIUM CONTAINING FLUORINE ATOMS IN ORDER TO REDUCE THE OCCURRENCE, ON THAT SURFACE, OF FLAWS LIABLE TO CAUSE STRESS CONCENTRATIONS WHEN SAID EDGE IS SUBJECTED TO TENSILE LOADING AND (B) CHEMICAL TEMPERING THE SMOOTHENED SURFACE OF THE EDGE; AND, PREVENTING SAID MEDIUM FROM CONTACTING CERTAIN PORTION OF THE SURFACE OF THE ARTICLE BY, PRIOR TO SAID STEP OF SUBJECTING THE SMOOTHENED SURFACE OF THE EDGE OT A RECTIFYING TREATMENT, PLACING A SHIELD MEMBER OVER EACH PORTION OF THE SURFACES OF THE ARTICLEE WITH WHICH CONTACT WITH SAID MEDIUM IS NOT DESSIRED AND PROVIDING A LIQUID FILM BETWEEN EACH SUCH SHIELD MEMBER AND THE UNDERLYING SURFACE PORTION TO BE SHEILDED.
