摘要： A method of making glass products includes: heating material to obtain a glass melt; heating the glass melt in a melting tank having a melting tank bottom, the glass melt having a melt volume, a melt surface, and a viscosity of 102 dPas at a temperature above 1580° C. The glass melt is heated such that at least some of the glass melt has a viscosity of 102.5 dPas or less. An amount of thermal energy introduced directly into the melt volume is more than 60% of a total amount of thermal energy introduced into the glass melt. A maximum difference between a temperature at a location on the melt surface and a temperature at a location at the melting tank bottom vertically underneath the location on the melt surface is such that a difference in glass melt densities is less than 0.05 g/cm3 per meter distance between the locations.

摘要： A glass article is composed of an aluminosilicate glass with at least one halogen with refining action in an amount ranging from 500 ppm to 8000 ppm and an Sn content of less than 500 ppm. The glass has less than 100 ppm As and less than 100 ppm Sb and the glass article has a thickness of less than 250 μm.

摘要： 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.

摘要： 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.

摘要： A method for producing a glass product is provided. The method includes providing a glass melt; hot forming the glass melt to obtain a glass product; and transferring the glass melt from a first region to a second region through a tube. The tube has a part that protrudes with a length into the glass melt in the first region. The part being at a distance from an inner base lying directly thereunder. The length and the distance are configured so that little defective glass gets into the tube and is transferred to the second region.

摘要： The present invention relates generally to a process for producing glass products and to an apparatus suitable for the purpose. In the process, a melting apparatus is provided with a melting tank for producing a glass melt from glass raw materials and a top furnace. Part of the surface of the melting region of the melting apparatus is covered with the glass raw materials and at least a small portion of the surface of the melting region is uncovered. In addition, energy is introduced in such a way that a vertical temperature difference can be established, such that the temperature of the glass melt at the base is greater than the temperature of the atmosphere in the top furnace.
