Melting of Noncrystalline Materials •In noncrystalline materials (glasses), a gradual transition from solid to liquid states occurs •The solid material gradually softens as temperature increases, finally becoming liquid at the melting point •During softening, the material has a consistency of increasing plasticity (increasingly like a fluid) as it gets closer to the melting point ©2002 John Wiley & Sons, Inc.
