Glassy materials became more important in the day to day life in various application such as the materials that gives protection from radiation, optical fiber materials for communication, etc. In the current work, MgO-ZnO-Cr2O3-K2B4O7 glasses are prepared and characterized to know more about the structural features about the prepared glasses. Melt quenching was used to make the samples. In this method, the high pure required chemical were weighed, heated them to melt congruently and then quenched to form the glass samples. The so formed glasses were then exposed to XRD, FTIR, and Raman spectroscopy were used to examine the glass samples. The lack of distinct peaks in the samples' XRD spectra helped to demonstrate the non-crystalline phase of the produced samples. Density values are measured for all the samples using the Archimedes principle and it is measured for three pieces of samples for each composition and averaged to get accurate values. The density data revealed that the values of the glass samples show clear increase from 2,343 to 2.406g/cc when MgO increases at the expense of K2B4O7. As a result of the transformation of BO3 units into BO4 units, the density has increased. FTIR data is taken from 400 cm-1 to 4000 cm-1, however the spectra drawn between 400 cm-1 to 1600 cm-1, since the data above 1600 cm-1 shows only the OH band. Metal cation vibrations were detected in the lower wavenumber side of the FTIR spectra, with BO4 units in the 800–1200 cm-1 range and BO3 units beyond the 1200 cm-1 range. The rises in the density of the samples are confirmed using FTIR spectra as well with the help of rising in the using BO4 units. Raman spectra recorded in the range of 200 to 1800 cm-1. Several borate groups, including diborate and penta borate, are visible in Raman spectra
