  • Science of Glass Making: How is Glass Made?

     · More specifically, glass is made by heating ordinary sand (mostly composed of silicon dioxide SiO 2) until it melts and turns into a liquid. You may wonder why the same thing doesn't happen on hot days at the beach, but the answer to that is quite simple— the melting temperature that the sand needs is very high, around 1700° Celsius.

  • Oil Sands 101: Process Overview | Oil Sands Magazine

     · Oil sands are actually found all over the world, and are sometimes referred to as tar sands or bituminous sands. A typical oil sands deposit in Alberta contains on average about 10% bitumen, 5% water and 85% solids, mostly in the form of coarse silica sand. Oil sands also contain fine solids and clays, typically in the range of 10 to 30% by weight.
