Abstract
A method for controlling alkali emissions of a glass element during hot forming is provided. The method includes the steps of: heating the glass element using one or more burner units each providing a burner flame to provide a heated glass element; sensing light emissions of a total light emitting area of the heated glass element and the burner flame of the one or more burner units via one or more sensor units; providing one or more signals of the one or more sensor units of the light emissions; comparing the one or more signals with one or more reference signals; determining, based on the comparing step, determined alkali emissions of the glass element; and controlling the one or more burner units based on the determined alkali emissions to adjust the alkali emissions of the glass element to a pre-given interval.
