A CONTINUOUS SHEET GLASS DRAWING PROCESS FOR THE PRODUCTION OF SHEET GLASS HAVING IMPROVED SURFACE STABILITY, WHICH COMPRISES FORMING A MASS OF MOLTEN GLASS, DRAWING A CONTINUOUS GLASS SHEET FROM SAID MASS, COOLING THE SURFACES OF SAID CONTINUOUS GLASS SHEET TO A TEMPERATURE OF ABOUT 100* F. TO ABOUT 400* F., PASSING THE SO-COOLED CONTINUOUS GLASS SHEET, WHILE THE TEMPERATURE OF THE SURFACE THEREOF IS WITHIN THE RANGE OF ABOUT 100* F. TO ABOUT 400* F., THROUGH AN ATMOSPHERE CONTAINING AT LEAST ABOUT 1000 P.P.M. BY VOLUME OF A SOLUTION IN A CHLORINATED HYDROCARBON SOLVENT OF AN ORGANOSILICON COMPOUND SELECTED FROM THE GROUP CONSISTING OF THE HYDROLYZABLE CHLOROSILANES AND BROMOSILANES, HAVING AT LEAST ONE ALKYL RADICAL CONTAINING AT LEAST 8 CARBON ATOMS BONDED DIRECTLY TO THE SILICON ATOM, THE HYDROLYSIS PRODUCTS OF SAID SILANES AND
