Fine structural detail found in electron micrographs of fracture surfaces of glass evidencing liquid‐in‐liquid colloidal immiscibility has been analyzed. Tail‐like structures emanating from the dispersed phase are related to the crack front propagation and are affected by the relative values of the cohesive strength of the dispersed phase and the adhesive strength between the dispersed phase and the matrix. The fracture surfaces of certain systems evidence depressions but fail to reveal complementary elevations. This apparent anomaly is shown to be the result of moisture attack on the dispersed phase.
