Glass as a material in its own right will always exist. But many new applications and manufacturing processes will involve glass in combination with other materials.
Optical fibres, for example, are currently manufactured with one or more different coatings, which are often plastics. With the increasing sophistication of opto-electronic devices, there is an increasing need to combine optical and electronic devices for many applications such as transmission of audio, video and data information.
Glasses and ceramics, either alone or composite with other materials, will find increasing application in biological and medical areas. Materials such as photochromic, electrochromic and thermochrominc glasses, which respond to external stimuli, are being developed with various, sometimes unusual, applications.
In the home we will see windows transform into TV screens, and other entertainment features as technology advances and more is possible.
