The results of a study of transparent glaze coatings synthesized in the system Na 2 O - K 2 O - B 2 O 3 - Al 2 O 3 - SiO 2 , with a mass content of 12.8% B 2 O 3 and 3.9% Al 2 O 3 . The effect of doubly charged modifier cations SrO, MgO, CaO and their combinations on the physicochemical properties and structure of glasses and coatings based on them has been established. The optimal range of compositions of glaze coatings that meet the requirements of standards for the migration of boron and aluminum into food media has been determined. Il. 2, bibliography: 3 titles.
