Summary 1. Existing views on the causes of opalescence in sodium borosilicate glasses are mutually contradictory and are not based on the quantitative study of the scattering of light in these glasses. 2. Investigation of Rayleigh scattering in sodium borosilicate glasses has established beyond doubt that there is a relationship between the scattering intensity and the structure of the glass. It has been shown that there are three temperature zones characterized by the way in which the intensity varies; a zone in which the intensity falls with rise in temperature, the opalescence zone, and the zone in which opalescence disappears. 3. In order to interpret the observed regularities, a deeper study of the structure of sodium borosilicate glasses will be necessary. A promising line of approach can be based on the relationship between the ability of sodium borosilicate glasses to become opalescent and their ability to form porous glasses by leaching, the structure of the latter being open to investigation by several independent methods.
