In an article in the Atlantic, glass was called humanity's most important material. In order to connect you and me, writes Douglas Main, these words are encoded into optical signals that travel at 300, 000 kilometers per second through fiber-optic cables, across mountains, underwater, across cities and countries, and across the globe. The glass inside these cables is thinner than a human hair and 30 times more transparent than the purest water. Glass allows us to see and be seen, to hear and be heard, to light up our rooms, our lives and our thoughts.

Switchable frosted glass, often referred to as smart glass, is a type of glass that can change its opacity on demand. When an electrical current is applied, the invisible electrochromic layer within the glass transforms from transparent to opaque, providing instant privacy. Conversely, when the current is turned off, the glass returns to its clear state. This dynamic feature makes it an ideal choice for various applications, from residential homes to commercial buildings.
