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.

A method for producing a glass product, comprising:
- 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, wherein the conduit system comprises a noble metal;
- and
- conducting an alternating electric current through the noble metal while conveying the molten silicate glass through the conduit system, the alternating electric current generating Joule heat in the noble metal, wherein the alternating current has a time integral over a positive and a negative half-wave that results in a zero value.
A glass product, comprising:
- a sheet-like glass product of a silicate glass having a thickness of at most 1000 μm and at least 15 μm;
- and
- less than four particles of a noble metal comprising material per kilogram of glass, wherein the less than four particles have a size of less than 200 μm.
