Frost-work glass is made by hot air drying of glue film coated on lapped glass surface. By experiments it is shown that the cause of frosting is the permanent strain in surface layer of lapped glass and contractive force of coated glue film. Further it is shown that glue film strips the surface of lens leaving tiny spots. Effect of stress in lens surface on the shape of stripped spots is discussed.
