A method for forming a lubricant layer on the surface of a glass and a method for manufacturing a glass using the same prevents scratches from occurring at the surface of a glass and decreases corrosion of glass manufacturing equipment. The method for manufacturing a glass includes forming a glass, supplying SOgas and a SOgas oxidation catalyst to the glass under an oxidation environment to form a lubricant layer at the lower surface of the glass, and annealing the glass.
