The rotational plasma process is a highly efficient method for melting fused silica. Using this method, we prepared glasses with different impurity proportions and examined their bubble contents. The majority of bubbles contained coal gases (type C), while a small proportion contained sulfur gases (type S). Type C bubbles are likely caused by carbon-containing impurities, such as graphite from the electrode. Type S bubbles may be caused by sulfur-containing impurities in the raw material. These results are consistent with those of other authors.
