摘要： A method for separating a portion from a sheet glass element having a thickness of at least 2 millimeters along an intended separation line that divides the sheet glass element into the portion and a remaining main part is provided. The method includes producing filamentary damages comprising sub-micrometer hollow channels in a volume of the glass sheet element adjacently aligned along the separation line; and heating and/or cooling the glass sheet element to cause expansion and/or contraction so that the portion detaches from the main part along the separation line. The portion and the remaining main part each remain intact as a whole. The step of producing the filamentary damages includes generating a plasma within the volume with laser pulses of an ultrashort pulse laser; and displacing points of incidence of the laser pulses over a surface of the glass sheet element along the separation line.

摘要： A component of glass or glass ceramic having predamages arranged along at least one predetermined dividing line is provided. The dividing line has a row of predamages lying one behind the other. The predamages pass continuously through the glass or the glass ceramic with at least 90% of the predamages being cylindrically symmetrical. The glass or the glass ceramic has a material compaction of at least 1% relative to an actual material density in a radius of 3 μm about a longitudinal axis of respective pre-damaged points. The relative weight loss per pre-damaged point is less than 10% and the component has a thickness of at least 3.5 mm.

摘要： The present invention relates generally to a process for producing glass products and to an apparatus suitable for the purpose. In the process, a melting apparatus is provided with a melting tank for producing a glass melt from glass raw materials and a top furnace. Part of the surface of the melting region of the melting apparatus is covered with the glass raw materials and at least a small portion of the surface of the melting region is uncovered. In addition, energy is introduced in such a way that a vertical temperature difference can be established, such that the temperature of the glass melt at the base is greater than the temperature of the atmosphere in the top furnace.

摘要： A method provides for producing modifications in or on a transparent workpiece using a laser processing device. The laser processing device has a short pulse or ultrashort pulse laser that emits laser radiation having a wavelength in the transparency range of the workpiece and which has a beam-shaping optical unit for beam shaping for focusing the laser radiation. The transparent workpiece is composed of a material that has a plurality of phases, of which at least two phases have different dielectric constants, of which in turn the one phase is a phase embedded in the form of particles, which phase is substantially surrounded by the other phase, and wherein the product of the volume of the particles specified in cubic nanometers and the ratio of the absolute value of the difference of the two different dielectric constants to the dielectric constant of the surrounding phase is greater than 500.

摘要： A glass container is provided that includes a tube, a circular bottom, and a longitudinal axis. A curved glass heel extends from an outer end the bottom to the first end of the tube. The outer surface has a topography defined by a function ĥ(x) that is an azimuthal average of a distance between a contact plane and the outer surface at any given position located on a circle having the centre and the radius |x|. The values ĥ for ĥ(x) are determined for a plurality of circles the radius of which increases stepwise by 500 μm starting with a circle around the centre having a radius of 500 μm. The values ĥ are determined in a range from x=−0.4×d2/2 to x=+0.4×d2/2, d2 having a size such that at least 4 values ĥ are determined and can be fitted with a curvature function h ^ ( x ) = - c × x 2 1 + 1 - c 2 × x 2 + h 0 .
