The manufacture of glassware articles of improved strength

摘要: An article of glassware, particularly a glass container, increased strength is made by process in which the parison treated manner will cause outer surface layer formed glassware to be state compression. Preferably glaze having coefficient thermal expansion lower than applied parison. Advantageously, flame spray method or dipping into fluidised bed containing powdered glaze. As an alternative, may capable being at least partially crystallised, after has been from parison, produce base article. Alternatively application glaze, chemically changed so that higher transformation temperature remainder Additionally, interior material producing active gases compressive produced on internal final article, balancing
