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： 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.
