abstract = "Correlative microscopy is used to compare the performance and nanophase structures of sodalimesilica, fused silica and borosilicate glasses using Vickers indentation crack analysis and the transmission electron microscopy (TEM) Fresnel contrast method. It is found that
the observed indentation cracking behaviour is correlated to the nanophase separation structure of these glasses. The so-called "normal" cracking behaviour of sodalimesilica glass is influenced by its spinodal nanophase separation; while the "anomalous" cracking behaviour of
fused silica is due to the uniform single phase structure. Borosilicate glass has a droplet nanophase separation and shows "intermediate" cracking behaviour. These results indicate that in order to produce low brittleness glasses it is important to control nanophase separation structure of
a glass.",
