The exploration of the new method of spectral basicity distribution – SBD - described in a recent work, continues by showing the possibility to represent the distribution of the structural nano-aggregates properties. Was chosen basicity, recognized as a leading property of oxide glasses, which correlates with all other properties, offering, in this way, very general information. Results obtained for sodium silicate glasses are presented. Interpreting the new data a concept was formulated, concerning the nano-heterogeneous structure of molten and solid glass.
