What Makes Glass Clear?

Glass naturally has a greenish cast because of the iron present in all sand. 1 Clear glass has been made clear by adding selenium which is a non-metallic element somewhat like sulfur. 1 The selenium gives glass a red tint that balances out the green color which results to a clear glass. 1 Other colors of the glass can be achieved by adding different chemical oxides to the ingredients such as cobalt is put in for blue, gold for ruby, manganese for purple, chromium or iron for green and uranium for yellow. 1

Other Colors of a Glass

Here are some common colors of a glass and its uses:

  • Clear glass is best used for alcohol, water, sauces and foods that are not affected by light. 2
  • Brown glass which absorbs the most ultraviolet radiation and it offers the perfect protection from the damaging effects of exposure to light due to the wavelengths shorter than 450 nanometer. 2Beer which is normally placed or brew in a brown bottle because it will be ruined by light absorption.
  • Green glass also has the light protection but not as much compared to a brown glass. 2 Some liquids such as wines and juices can be exposed to some light without ruining their flavors so they are usually bottled or contained in a green glass. 2
