Abstract: A method of making a glass product includes: melting a batch of raw materials to form a glass melt in a melting tank; heating the batch and/or the glass melt using two or more electrodes, the electrodes including an electrode material and heating the batch and/or the glass melt includes operating the electrodes at a current frequency of at least 1,000 Hz and at most 5,000 Hz; withdrawing the glass melt from the melting tank; and forming the glass melt into the glass product.

Abstract: A method for producing a glass product, preferably a sheet-like glass product, is provided that includes conveying a molten silicate glass through a conduit system from one area of a glass product producing installation to another area of the glass product producing installation. The conduit system includes noble metal and is configured to conduct an electric current through the noble metal so as to generates Joule heat in the conduit system. The current is an alternating current for which the time integral over a positive and a negative half-wave results in a zero value.
