Two major sources of experimental error are examined in the analysis of small‐angle X‐ray scattering (SAXS) data from weakly scattering or nearly homogeneous multiphase glasses. The effect of sample surface structure and the importance of a well‐polished surface are examined. There is also a contribution to the measured SAXS from the homogeneous matrix or solvent structure of the glass. This contribution arises from short‐range frozen‐in density fluctuations within the glass. A method for correcting this contribution before analyzing for particulate microstructure is described. In addition, SAXS curves for several commercial glasses are presented.
