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 glass article is designed at least in part in the form of a glass tube element including at least one shell which encloses at least one lumen. For at least one light transmission analysis of the glass article, a ratio of an average amplitude transmission factor and a specific amplitude transmission factor is greater than 1.00001.

IPC: C03C3/118

Abstract: The disclosure relates to a glass product or glass composition, and to a method of making a glass product. The glass composition can be manufactured without inhomogeneities in the glass melt and with sufficiently uniform and isotropic properties in the obtained products. The glass compositions further minimise and/or overcome the problem of blockage of pipes, liners, ducts or nozzles during the manufacture of high-quality glasses.
