An apparatus and a method for producing glass products from a glass melt, avoiding bubble formation, are disclosed, wherein the apparatus includes a crucible and an internally component for processing the glass melt, and wherein, for heating the glass melt, the apparatus comprises an AC generator which energizes the crucible or stirring crucible via electrical connection elements. The component or stirring system is connected via a current-limiting choke having a variable impedance with the power supply elements. The impedance of the current-limiting choke is adjusted so that a AC density existing in the glass melt lies between a lower limit value and an upper limit value. By means of a choke and by adjusting the impedance it can be achieved that the AC load of the system can be minimized and that simultaneously the water decomposition reaction at the precious metal surfaces can positively be influenced.
An apparatus for producing glass products from a glass melt (G) under avoidance of bubble formation, the apparatus comprising a crucible, and arranged therein, a component for processing the glass melt (G), wherein the apparatus for heating the glass melt (G) comprises an alternating current unit that feeds the crucible with current via power supply elements, and wherein the component arranged in the crucible is connected to one of power supply elements of the crucible via a current-limiting choke having an impedance (ZD) that can be variable.
A method for the production of glass products from a glass melt (G) while avoiding formation of bubbles, wherein the glass melt (G) is processed in a crucible by means of a therein contained component, and wherein for heating the glass melt (G) the crucible is energized via power supply elements which are connected to an alternating current generator, wherein the component arranged in the crucible is connected with the power supply elements of the crucibles via a current-limiting choke having a impedance (ZD) that can be variable.
