We can thank Leigh Adams for this blog…she found some information online regarding spray on liquid glass. Spray on liquid glass? More information can be found on the web site Physorg.com. It’s a silica based substance that when sprayed on a surface creates an impenetrable surface that sterilizes with ease. It’s being used in situations such as food handling and hospitals and is proving to be very practical as a means of keeping surfaces coated with it clean for long periods of time. It was invented in Turkey and is being tested in Germany and the UK. It’s fascinating and I look forward to seeing what other applications this glass product will be used for.
