Final answer:
The mixture of silica and fluxes fused at a high temperature to make glass is called frit, necessary for lowering the melting point of glass during the glassmaking process.
Step-by-step explanation:
The mixture of silica and fluxes that is fused at a high temperature to make glass is known as frit. This material forms a part of the glassmaking process, where it acts as a crucial component ensuring that the glass melts at a lower temperature and can be shaped as desired.
Glazes also involve fluxes and can be applied to pottery, but they are not the same as the frit used in glassmaking. It's not to be confused with mosaic, which is an art form consisting of assembling small pieces of colored glass, stone, or other materials; nor with enamel, which refers to colored glass in powdered form that is fired onto a metal surface, as in cloisonné.
