Darn, was hoping for something cool . :( I wonder how it got that glass look and feel ?? 

Glass is made from sand..silica, the glass look is from silica that was part of the impurities in whatever was being refined.

Glass (silica) is used to flux metal when smelting. Molten metals will oxidize rapidly. So silica (quartz, glass, etc.)is added to the furnace to cover the molten metal and keep it away from oxygen. 

The glass in the furnace works exactly like the silica covering an arc welding rod or the shielding gas in a MIG or Heli arc process. Any time you melt or weld metal there is something to keep it from gobbling up oxygen. Smelting under a puddle of molten glass is the cheapest and most popular way to accomplish this.
