摘要

Process for injecting gas into a glass melt comprises introducing the gas stream into the melt in a pulsed manner; and interrupting the gas stream between two subsequent pulses. The pulses last for less than 1 second. Preferred Features: The pulses last for less than 100 ms or less than 50 ms. The gap between two subsequent pulses is at least 1 second. The melt is liberated from foreign gases by rinsing with oxygen.
