Spray-on liquid glass is transparent, non-toxic, and can protect virtually any surface from water, dirt, heat, and bacteria. The coating is flexible and breathable, which makes it suitable for use on an array of products. Liquid glass was invented in Turkey and the patent is held by Nanopool, a family-owned German company. In the home, spray-on glass would eliminate the need for scrubbing and make most cleaning products obsolete. Since it is available in both water-based and alcohol-based solutions, it can be used in the oven, in bathrooms, tiles, sinks, and almost every other surface in the home, and one spray is said to last a year. Liquid glass spray is perhaps the most important nanotechnology product to emerge to date. It will be available in stores soon, with prices starting at around EUR 5.70. However, supermarkets may be unwilling to stock the products because they make profits from cleaning products, which liquid glass would make obsolete.
