Does melting sand actually make glass? - Quora

However the melting point of sand is light years away from Earth. Well, some 3000 F or so. In the process sodium carbonate is being added to lower that point. Calcium carbonate then will prevent the glass from dissolving in water. Also a variety of chemical compounds can be added to reach higher quality (pyrex, bullet proof, etc).

Melting, Remelting, and Casting for Clean Steel - …

The metal quality in the melting furnace is almost certainly excellent as a result of the time available for inclusions to float out. This quality is destroyed by the pour into the ladle, but is largely, but not completely, restored prior to casting. Unfortunately, more damage is to be expected by turbulence introduced during casting. This is particularly important because any …
