“SiO2- ultra thin layering” is the technical term for Liquid Glass. Apart from a select group of professionals, few people in the UK know about this stunning technology. If you walk around Ataturk’s Mausoleum in Ankara you are walking on it; if you visit certain hospitals in the UK you are touching it. If you see an unusually clean train you are probably looking at it, and if you wonder how your white settee looks so clean, you may be sitting on it. All of these surfaces have been coated with invisible glass.
Spray-on glass?
A German company has developed an SiO2 spray compound that apparently can be applied to just about anything.
