Crystallized glass "Neopariés" is a kind of  glass building material, made by the highly sophisticated and specialised technique of crystallization of glass in 1970's. It is also oldest crystallized glass series material.

Neopariés is a versatile building material having a marble-like texture and greater strength and resistance to weathering than granite. It is used for exterior and interior walls of buildings, and for counter tops and table tops. Neopariés can also be formed into columns and curved corners, as it requires only a simple process to make a curved panel. It is most cost effective.

Its shortcoming is easy to dirty, so it usually hadn't applied to floors, especially in floors of big public building.
