Abstract: A method of making a glass product includes the steps of: melting a batch of a plurality of glass raw materials in a melting tank to form a glass melt; heating at least one of the plurality of glass raw materials and the glass melt using at least one fuel burner by reacting hydrogen and oxygen; withdrawing the glass melt from the melting tank; obtaining a glass product, the glass product having an Fe2+ to Fe3+ ratio of less than 0.2 or less than 0.05 and having at least one of less than 80 bubbles in a size range of from 0.1 mm to 0.2 mm per 10 kg of glass and less than 2 bubbles of a size larger than 0.2 mm per 10 kg of a glass.

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.
