1100 °C

Sodium tetraborate (Na2B4O7.10H2O), analyzed reagent was dried overnight at 150° C, mixed with the appropriate quantity of dopant ions and homogenized in an electric homogenizer (vibrator) during 10 minutes. The material was then transferred to a platinum crucible and heated at 1100° C for at least 30 minutes, until a clear transparent solution was obtained. The glass matrix loses water and the composition of the matrix is after the heating 35(Na2O).65(B2O3). A drop of the hot melt was allowed to fall directly onto a clean white glazed ceramic surface, into the center of a space ring of 1 mm thickness, and pressed with a second ceramic tile to produce a glass disk of 1 mm thickness and an approximate diameter of 12 mm. The glass is transparent in the ultraviolet and in the visible part of the spectrum.
