Weathering phenomena occurring during storage of tableware glasses with the different chemical composition have been examined using Scanning Electron Microscopy (SEM) and Electron Diffraction X-Ray Analysis (EDX). The tumblers of different chemical composition of tableware glass, crystalline type, have been prepared in a pot furnace. They have been packed in paper boxes and placed in the storehouse. Samples were withdrawn after 4 months, one and half year and 4 years. The SEM and EDX analysis have been done from the inner surface of the samples as well as concentration profiles of the glass wall have been measured by EDX. Relevant differences in surface layer chemical composition were observed. The comparison of the Na2O and SiO2 change is discussed in connection with the glass weathering resistance of different glass composition.
