What prevents these tetrahedra from forming a crystalline network is that the extended 3-dimensional network is irregular and the Si-O-Si bonds random (McLellan and Shand, 1984). The shared oxygen atoms are called bridging oxygens. In pure silica glass, the ratio of silicon to oxygen is ideally 1:2 and all oxygen atoms are bridging.
