摘要

Process for injecting gas into a glass melt comprises feeding the gas stream into the melt with a pulsed throughput; and interrupting the gas stream between two subsequent pulses. One pulse lasts for less than 1 second. Preferred Features: One pulse lasts for less than 100, preferably less than 50 ms. The pressure of a pulse falls from a maximum to zero within a time span of less than 100, preferably less than 50 ms.
