摘要

Transporting, homogenizing and/or conditioning a glass melt comprises adjusting the residence time of the melt in a transporting and/or conditioning device using a section of a wall of the device so that the diffusion barrier layer reduces diffusion of hydrogen through the wall and the partial pressure in the melt is less than 1 bar. Independent claims are also included for the following: (1) a device for carrying out the above process; and (2) glass, preferably an optical glass, produced using the above process.
