This article examines the process of the analysis of gases in bubbles. A knowledge of the identity of the gases which are found in bubbles and in solution in glass can often be of great use to the glass Technologist. The bubbles which may occur in bottles, in chemical glassware, in articles such as glass blocks, in sheet glass and the highest quality plate glass, in CRT's and in optical glass can cause considerable loss to the manufacturer; any information which contributes to their prevention is valuable. In addition, the examination of bubbles has great scientific interest, since it gives information about the melting process and the behaviour of refractory materials. The determination of dissolved gases adds to our knowledge of the effect of such gases on the properties of glass and of the ways in which they can enter into its structure.
