Recipe Details

SiO2, CaCO3, Na2CO3 and 2% of samarium oxide (wt%) were used as starting materials. Approximately 25 g batches were mixed and melted in platinum crucibles in an electric furnace at 1500 °C for 3 h in air. The melted glasses were quenched at room temperature and further annealed at ca. 550 °C for 1 h. The glass samples were cut and carefully polished.
