The flow and bubbles motion in BaO-P2O5 or BaO-P2O5-Sb2O3 glass melts in a high magnetic field up to 2.0T was observed. No apparent change of flow characteristics in BaO-P2O5 glass melts was found. However, the frequency of bubble nucleation evidently decreased with the field strength. At a field strength of 2.0T, almost no nucleation of bubbles was observed. The majority of the bubbles were annihilated at the surface of the melt. This effect may apply to many optical quality glasses to be obtained bubble-free.
