From sand to glass

Prized by the ancient Egyptians, mentioned in the Holy Scriptures in the 5th century BC, described by Pliny the Elder two centuries before Christ, glass is one of the oldest materials manufactured by mankind. However, the formation obtained from powder granules heated to high temperature still contains shadow zones. It wasn’t until 2012 that a team of researchers led by the Frenchman Emmanuelle Gouillard (CNRS/Saint-Gobain) managed to visualize glass formation in real time on the inside of the material thanks to X-ray tomography, a powerful 3‑D imaging technique


The Vitralys® app is the Belgian sectoral reference calculation tool for glazing thickness in accordance with the semi-probabilistic calculation method from the NBN S 23-002-2:2020 standard.

Compliance with standardization and the rules of the art is a top priority for the glass sector.
