Abstract: A glass article is provided that has two plane-parallel main sides, a thickness between the two plane-parallel main sides of less than 3.0 mm, an average near-surface level of damage (ONSL) on each of the two plane-parallel main sides, and an average location-thickness variation (ODS) normalized with respect to the thickness on the specified measuring area. The average near-surface level of damage is less than 2000 damages with an extension of less than 1.0 ?m. The specified measuring area is 2×2 mm2. The average location-thickness variation (ODS) normalized is less than 10 nm per Rm thickness of the glass article. The average location-thickness variation (ODS) is a difference between a highest thickness and a lowest thickness within the specified measuring area.

Abstract: A method for packing flat substrates, more particularly glass substrates, in a packaging box is provided. The method include the steps of: providing a base part of the packaging box, the base part comprising a lower wall and preferably four side walls, placing a flat substrate directly or indirectly on the lower wall of the base part of the packaging box, placing an intermediate layer directly or indirectly on the placed flat substrate, forming a stack of flat substrates and intermediate layers therebetween by repeating the preceding two steps, and setting a cover part of the packaging box on the base part of the packaging box.

Abstract: An apparatus for shaping a workpiece made of glass using minimum lubrication is provided. The apparatus includes device for heating the workpiece, a shaping station with at least one forming tool for shaping the workpiece, and at least one spray nozzle for applying an oil as a lubricant onto the surface of the forming tool. The forming tool exhibits heat dissipation such that the temperature on the contact surface of the forming tool during the shaping process is kept below 300° C. The amount of oil dispensed by the spray nozzle per forming step and application instance is less than 0.1 g.

Abstract: A process for producing a glass article is provided that includes, in order, a first process step in which a surface of the glass article has a temperature of at least 400° C. for at least some of the time, a second process step in which the surface of the glass article has a temperature of more than 10° C. and less than 100° C. and the surface is brought into contact with water or water vapor and the surface of the glass article is supplied with an amount of water which corresponds to a water layer thickness of from 1 to 100 ?m, and a third process step in which the glass article is processed further with contact of the surface with foreign materials or other glass articles.

Abstract: An apparatus is provided for drawing glass ribbons from molten glass. The apparatus includes a drawing tank for holding the molten glass and a guiding body. The tank has a lower nozzle opening through which the molten glass can exit downwards. The nozzle opening has two nozzle slots defined between the guiding body and edges of the nozzle opening. The guiding body protrudes downward out of the nozzle opening. The guiding body is supported so as to be spaced apart from the edges with the guiding body suspended in a self-supporting manner at least along a central section of the nozzle opening.

Abstract: An apparatus is provided for producing thin glass ribbons from molten glass. The apparatus includes a drawing tank, a direct heater, and an indirect heater. The drawing tank has a lower elongated nozzle opening through which the molten glass can exit downwards. The direct heater has one or more heating circuits operable to heat the drawing tank in a first heating zone. The direct heater has a power source for each on the heating circuits. Each heating circuit has connections to connected to a wall of the drawing tank so that current from the power source flows through at least a portion of the wall and heats the wall. Each heating circuit also includes current-carrying portions of the wall. The indirect heater has one or more heating elements to heat the drawing tank in a second heating zone.
