Spinning Process Melting Temperature
The process of converting solid glass marbles into fibers requires them to be melted into a molten state before being extruded through a spinneret.
For the spinning process of glass marbles into fibers, the material must reach a high molten temperature. The specific temperature required is $1371^{\circ}\text{ C}$.
Spinneret Feeding Requirement
Feeding molten glass marbles into a spinneret necessitates reaching a temperature sufficient for proper flow and extrusion. This high temperature ensures the glass is in a viscous liquid state suitable for forming fine filaments.
Therefore, the glass marbles are subjected to melting at $1371^{\circ}\text{ C}$ before feeding to the spinneret.
