<P>PROBLEM TO BE SOLVED: To provide a method of working an optical glass used for optical components such as an infrared cut low pass filter of a CCD camera or a flourophosphate based glass into a sheet. Ž<P>SOLUTION: The method of working an optical glass into the sheet is carried out by holding a plurality of places of each of the four sides of the rectangular optical glass 16 by a glass holding member 8 constituting a two dimensional magnification mechanism E to arrange them in a heating furnace 1 in the vertical direction, operating the two dimensional magnification mechanism in the heating furnace having a controlled set temperature at which the glass is deformable to magnify the distance among the plurality of the places while drawing each of the plurality of the places of the four sides, by the glass holding member, in the right angular direction of the side to two-dimensionally draw the optical glass to form the sheet.
