What is it about?
An international team of researchers has developed a glass material with the ability to deform plastically at room temperature without fracture. The discovery may revolutionise the way glass materials are used in modern applications.

Why is it important?
Conventional flat glass is primarily made up of silicon oxide and cracks easily because the atoms in the glass are not able to move when subjected to stress. If the glass is bent or stretched too hard, it will break. Traditional glass manufacturing processes allow glass to moulded into any shape, but they require a high temperature. “In the traditional process, glass is heated to a molten state. I am sure we have all seen glass blowers handling red-hot glass,” Frankberg says. The demonstrated glass ductility is however achieved at room temperature.
