Abstract: A thermally tempered glass element is provided made of glass with two opposite faces that are under compressive stress of at least 40 MPa. The glass has a working point at which the glass has a viscosity of 104 dPa·s of at most 1350° C. The glass has a viscosity versus temperature profile and a coefficient of thermal expansion versus temperature profile of the glass are such that a variable (750° C.−T13)/(CTELiq−CTESol) has a value of at most 5*106 K2. The CTELiq is a coefficient of linear thermal expansion of the glass above a glass transition temperature Tg, the CTESol is a coefficient of linear thermal expansion of the glass in a temperature range from 20° C. to 300° C., and the T13 is a temperature at which the glass has a viscosity of 1013 dPa·s.

Abstract: The present invention relates to glasses having a composition made up of base glasses. The glasses have a good chemical toughenability in combination with an advantageous coefficient of thermal expansion. Owing to their composition and the production process, the homogeneity of the properties of the glasses at their surface is high compared to the bulk glass. Furthermore, the fragility of the glasses is low, so that they can be processed to produce very thin glass articles.

Abstract: Glass elements are provided that include a coating and a sheet-like glass substrate. The sheet-like glass substrate has a first surface and a second surface opposite the first surface. The coating is disposed in at least some areas of at least one of the first and second surfaces. The coating is an inorganic glass-based coating that includes at least one glassy component; at least one pigment comprising pigment particles; and a filler. The filler is inorganic and includes filler particles with a d50 value, based on an equivalent diameter, of at least 0.1 μm and less than 10 μm.

IPC: C03C3/093
Abstract: A glass having a good hydrolytic resistance and alkali resistance is defined by a targeted combination of stoichiometric glasses, including glasses also existing as crystals in the same stoichiometry and whose properties can be assumed as being very similar due to the identical topology of the structural units for glass and crystal, respectively. A process of producing the glasses is also provided.
