摘要： The invention relates to a glass vessel having at least one wall and manufactured from a base material which is an alkali-containing silicate glass. It is a feature of the glass vessel that at least a surface layer is enriched in potassium and depleted of sodium and/or lithium, while an inner layer, especially one directly adjoining the surface layer, is not enriched in potassium and not depleted of sodium and/or lithium, and that the glass vessel has compressive stress up to a compressive stress depth and tensile stress beyond the compressive stress depth, wherein the tensile stress rises with increasing depth up to a tensile stress maximum within the inner layer and/or wherein the progression of the tensile stress as a function of depth does not have a linear section and/or wherein the progression of the tensile stress as a function of depth does not have a section in which tensile stress is constant.

摘要： The invention relates to a flat glass pane made of a base material, which is an alkali-containing silicate glass. The flat glass pane is characterized in that at least one surface layer is enriched with potassium and is depleted of sodium and/or lithium while an inner layer, in particular an inner layer directly adjoining the surface layer, is not enriched with potassium and is not depleted of sodium and/or lithium; and the flat glass pane has a compressive stress up to a compressive stress depth and a tensile stress starting from the compressive stress depth, wherein the tensile stress increases as the depth increases up to a tensile stress maximum arranged in the inner layer, and/or the curve of the tensile stress does not have a linear section depending on the depth, and/or the curve of the tensile stress does not have a section in which the tensile stress is constant depending on the depth.

摘要： The invention relates to a method for producing a glass article. The method includes the step of producing a glass body from a glass material and the further step of bringing the glass body, at a primary temperature which is at most 50 Kelvin below and at most 30 Kelvin above the Littleton softening point of the glass material, into contact with a liquid cooling agent which has a cooling agent temperature which is at least 200 Kelvin and at most 550 Kelvin below the primary temperature.
