Presentation transcript:

Glass Aims: describe how sodium carbonate is used to make glass describe the role of transition metals and sodium carbonate in making glass describe aspects of safety, sustainability and effects on the environment of glass

Have you ever wandered? How is glass made and coloured? What are the problems of using glass?

Raw Materials Sand (silicon dioxide) But this melts at 2000oc so.. Sodium carbonate is added This lowers the melting point to 1000oc, but… This is very weak and can dissolve in water so… Calcium oxide (lime) is also added

Other types of glass Crystal Plus potassium oxide an lead oxide Refracts light differently

Pyrex Boron Low expansion rate so less cracks form

Other types Fibre glass – loft insulation Glass ceramic – cooker tops Crown glass – lenses

What are the most abundant elements on Earth? Oxygen Silicon Aluminium Iron Calcium Sodium Potassium Magnesium Titanium Hydrogen
