Turkish scientists have developed spray-on liquid glass that is transparent, non-toxic, and can protect virtually any surface against almost any damage from hazards such as water, UV radiation, dirt, heat, and bacterial infections, making cleaning products unnecessary. The invisible coating is also flexible and breathable, which makes it suitable for use on an enormous array of products.

The liquid glass spray consists of almost pure silicon dioxide (silica, the normal compound in glass) extracted from quartz sand. Water or ethanol is added, depending on the type of surface to be coated. There are no additives, and the nanoscale glass coating bonds to the surface because of the quantum forces involved.
