   The resultant molten glass will be glass. When glass cools slowly, it is   
   a crystallization process.

   What do you think they do with the remaining sand that's already at the    
   temperature of molten iron?

   Sand is not iron ore, but sand is in iron ore.   
      
   You've just proven yourself too stupid to be an engineer.
