A challenge to invent the material of a glass-ceramics type with a network of nanocrystals in the glassy matrix by means of a glass controlled crystallization is presented in the paper. The structures occur at the time of a glass heat treatment. The studies were carried out on fluoroindate glasses doped with rare-earth elements. Controlled crystallization was performed in order to obtain transparent glass-ceramics: the network of nanocrystallites (or at least microcrystallites) with higher content of rare earth ions in comparison to their content in the glassy matrix. In order to compare the initial glass and the new material of a glass-ceramics type properties, several experimental techniques were emloyed like X-ray diffraction (XRD), electron probe microanalysis (EPMA), differential thermal analysis (DTA), differential scanning calorimetry (DSC) and luminescence measurements.
