Abstract
A method and device for nozzle-injection of gas into molten glass is disclosed wherein a gas stream is introduced into the molten glass in a temporally pulsed throughput such that the gas stream is interrupted between two sequential pulses, the duration of each pulse amounting to less than one second.
Claims8
Method for nozzle-injection of gas into molten glass, comprising:
- 1.1 introducing a gas stream into a molten mass in a temporally pulsed, throughput;
- 1.2 interrupting the gas stream between two sequential pulses by creating a pressure-free phase;
- 1.3 wherein duration of the pulses amounts to less than 1 s and wherein following the pulse the pressure falls from a maximum value to null within a time span of less than 100 ms.
Dependencies are inferred from the claim text.
