Abstract:
Weathering phenomena occurring during storage of tableware glasses with different chemical compositions were examined using Scanning Electron Microscopy (SEM) and Electron Diffraction X-ray analysis (EDX). The tumblers of different chemical compositions of tableware glass, crystalline type, were prepared in a small tank furnace. They were packed in paper boxes and placed in the warehouse. Samples were removed after 4 months, two years, and 4 years. The inner surface of the samples was analyzed with SEM and EDX. In addition, concentration profiles of the glass wall were measured using EDX. The comparison of the SiO2 change is discussed in connection with the glass weathering resistance of different glass compositions. The presence of large amounts of corrosion products, microcracks in the surface layer, and a significant difference in SiO₂ content between the surface and the bulk glass indicates low weathering resistance in glass with less than 1% Al₂O₃ and without ZnO, ZrO₂, or TiO₂.
