Not exactly. It was once called a supercooled liquid, because it was cooled too fast to crystallize (as quartz). There is a common story about glass flowing, and that windows in centuries-old buildings got thicker at the bottom because of the flow. That story is false; it has been disproven. Glass does not flow. The state of glass is better described by the more recent term, "amorphous solid". This describes a substance that would have crystallized if it had been cooled more slowly, but since it was cooled rapidly it formed a solid with a random structure.

Glass is a liquid albiet a very slow moving one. I do not know the physic of it. However, if you were ever to measure a pane of glass from a very old window, the top of the pane would be thiner than the bottom because the glass flowed downwards. That is why restores tend to flip the window pane when they restore an old window. Saw that on: Ask This Old House.

at high temperature glass becomes liquid. Its like ice to water.

glass is a mixture of sodium silicates and aluminates at high temperature...it is cooled to a very low temperature and it solidifies. Glass is a supercooled liquid.
