Known methods of producing a three-dimensional glass object comprise the step of shaping of a glass fiber, wherein the glass fiber provided with a protective sheath is fed continuously to a heating source, the protective sheath is removed under the influence of heat, and the glass fiber is softened. In order to facilitate the production of filigree or optically distortion-free and transparent glass objects as much as possible, and also enable the adjustment of optical and mechanical properties with high spatial resolution, in one aspect the glass fiber has a protective sheath with a layer thickness in the range of 10 nm to 10 μm.

A drawing method for glass is described. The method provides glass components that have a strongly increased ratio of width to thickness when compared to the preform, which makes the manufacturing of flat glass components more economical. The method purposefully controls the temperature distribution within the preform.

An electrical heating conductor arrangement for heating a furnace has one or more strip-shaped portions with a generally horizontal sheet-like extent. The strip-shaped portions are formed by individual bands which have along their width an arcuate curvature with respect to a horizontal plane. The individual bands are partially mounted by at least one bearing element pivotably in the longitudinal direction of the respective band.

A method of forming a glass container includes providing a glass parison having a tubular wall that includes an inside surface, which defines an interior parison cavity open at one axial end of the tubular wall, and an outside surface. The tubular wall includes an expandable blow portion that has a forming viscosity between 10.sup.7.5 Pa.Math.s and 10.sup.5.5 Pa.Math.s and is also in an isoviscous state. The glass parison is blow molded into a glass container by introducing a compressed gas into the interior parison cavity to thereby cause the expandable blow portion of the tubular wall to expand outwardly into a portion of a wall that defines the glass container.

A glass container production line includes N workstations configured to perform respective production steps on glass containers being processed along the line, wherein Nis an integer at least equal to 1; M heating devices associated with at least a part of the N workstations to heat portions of the glass containers being processed, wherein M is an integer at least equal to 1; wherein the M heating devices respectively comprise M microwave sources and M adjustment units operatively associated with the M microwave sources, each of the M adjustment units being configured to adjust in power the respective microwave source; wherein the M microwave sources are microwave generators of the solid-state type; and wherein the M adjustment units are configured to adjust a power of the respective M microwave sources with an adjustment time of less than 100 ms. An associated glass container production process is also described.
