Requirements to properties of protective-technological coatings for the tin bronze melting from secondary raw materials were formulated in the work. The choice of model glasses compositions in the initial Na2O-B2O3-SiO2 system on the basis of the melting parameters values was made. Non-scarce and inexpensive raw materials for protective coatings were selected. Also the best glass composition was determined based on the complex of chosen properties. The formation mechanism of the selected composition glassy melting by using DTА and XRDА was studied.
