Beschreibung
Zusammenfassung:	The invention relates to a glass article, the chemical resistance of which is elevated and improved in relation to known glass articles. In particular, the invention relates to an article of soda-lime-silica glass comprising at least one surface and a core zone having a substantially constant concentration of aluminium and having directly under said surface a concentration of aluminium dissolved in the glass measured by EELS at least 1.2 times higher than that of the core zone. L'invention porte sur un article en verre, dont la résistance chimique est élevée et améliorée par rapport à des articles en verre connus. En particulier, l'invention porte sur un article en verre sodocalcique comprenant au moins une surface et une zone centrale ayant une concentration pratiquement constante en aluminium et ayant, directement sous ladite surface, une concentration en aluminium dissous dans le verre, mesurée par spectroscopie de pertes d'énergie d'électrons (EELS), au moins 1,2 fois plus élevée que celle de la zone centrale.
