1. The intensity of the scattering of light by sodium borosilicate glasses increases which increase in the duration of heating at constant temperature in the opalescence zone. 2. When the glasses are heated at constant temperature in the opalescence

1. The scattering intensities of specimens having the “direct” and “reverse” structures coincide precisely as far as the terms determining the zero-angle scattering: on the basis of the diffraction photograph it is impossible to make a choice

Direct experimental evidence in favor of the hypothesis of a chemically heterogeneous structure in complex glasses has been obtained by means of x-ray diffraction [1,2] and electron microscope [3–7] studies of multi-component glasses carried out in

For study of the initial stage of the crystallization of glasses it is important to know their submicroscopic structure. This can be achieved by studying the scattering of x-rays at low angles; detection of such scattering provides direct proof of he
