Week 8 - Glass Research

• Although glass is brittle, it is extremely durable and can be moulded into any shape.
• Glass doesn’t really decay; instead it crystallises, weathers and erodes. The rate of crystalisation is depended on many factors, most importantly temperature.
• If glass is in the ocean for a prolonged period of time, its edges will go smooth from erosion.
• The melting point of glass is between 800 and 950 degrees Celsius. In extreme heat, glass will become soft and increasingly liquid.
• Spalling of glass is created by rapid cooling such as the application of water. This causes small close cracks.
