Alternative for fine pure silica in kiln-casting glass molds
The most common type of refractory is silica in the form of quartz. Silica is the most plentiful mineral on Earth [11]. The melting temperature of pure silica is around 1710 °C [12]. Even silica being easily found in nature, for its use in kiln-casting molds it undergoes a broad process of refining to get on fine granulometry (37–74 µm).
