The more recent results concern the structure of water confined in a Vycor glass [37], which is a porous silica glass characterized by a quite sharp distribution of cylindrical interconnected pores and hydrophilic surfaces. We comment on some results that have been obtained as a function of level of hydration from full hydration (0.25 g water/g dry Vycor) down to 25% and temperature [38]. Based on the information that the dry density of Vycor is 1.45 g/ml, the porosity 28%, and the internal cylindrical pores of cross-sectional diameter 50 A, the 50% hydrated sample has three layers of water molecules on its internal surface and a 25% hydrated sample corresponds roughly to a monolayer coverage. 

Long-term studies performed by the CEA (French Atomic Energy Commission) resulted in the formulation of the so-called R7 and T7 glasses. Characterization studies have verified the main properties of the final products and have established the glass specifications. The vitrified waste specifications were subjected to peer review by an independent commission of nuclear specialists.

The lattices with localized bonding electron pairs and the glasses characterized by localized bonding functions have wide forbidden bands. 

Refractive index is the most useful physical property in forensic glass characterization. It can be measured to a high degree of accuracy and precision, which is essentially independent of fragment size. The RI of a glass depends upon the combination of raw materials used, together with the nature of the manufacturing process.
