1.4 Glass is basically an amorphous solid. When glass is made the silica is cooled from its liquid state, and it does not solidifies even when the temperature is dropped below freezing point. Hence, glass is a super cooled liquid. Due to this fluidity property, glass can be considered as a liquid of extremely high viscosity. The evidence of the fact can be seen in the windows getting thicker at bottom over a period of time.
