FIELD: chemistry. ^ SUBSTANCE: invention relates to method and device for glass strengthening. Formed glass products are submerged into salt melt bath, containing potassium ions, for 10 seconds or less. Glass product surface temperature during submergence stage equals at least temperature of glass fritting. Glass product is kept at temperature within the range from point of glass deformation to temperature, approximately 150C lower than point of glass deformation, during at least approximately five minutes. ^ EFFECT: increase of bottle strength and reduction of time for bottle processing in salt melt. ^ 38 cl, 14 ex, 5 tbl, 24 dwg |
