In contemporary life, most of us rely on glass more than we think: glass is not only used in our windshields and Windows, but also in the optical cables beneath our feet, which are of great significance. Now we look at each other through a glass screen, Mauro said in an interview. It made me acutely aware of the fragility of our connection. We spoke via Zoom, a remote online video conferencing software. Mauro continued: Without glass, we would not have tablets, mobile phones, a range of information terminals. All of this is transmitted by light signals using ultra-fine glass wires that we call fiber optics. Without glass, he says, we wouldn't be able to appreciate modern architecture, artificial light, natural light, cars, and most importantly, such a wealth of information.

The term float glass refers to a method of glass production that involves floating molten glass on top of molten tin. This technique, invented in the 1950s, results in a flat, smooth surface that is ideal for various applications. French green float glass, specifically, is produced through this method, whereby the incorporation of iron oxide lends it a subtle green tint. This coloration varies, depending on the thickness of the glass and the specific manufacturing process, resulting in a spectrum that ranges from a soft emerald to a deeper forest green.
