Glass is made from three substances. Here are the most common:

  • Pure silica has a melting point around ___________ degrees Celsius. The substance alone could be used to make glass, but two other substances are added to simplify the production.
  • Soda, sodium carbonate, or potash lowers the melting point to ___________ degrees C but makes the glass water-soluble.
  • Lime, calcium oxide, is added to restore ___________.

Read through the questions below before watching the video. While watching, explore the process of how glass art is created.
