Watch Sapphire Glass vs Concrete block in this new video
Synthetic Sapphire Glass
We've all heard Sapphire Glass being used in smartphones (more notably as the covering for the Apple iPhone 5S Touch ID fingerprint scanner), but few realize just how tough it really is. While it may be seen as a premium and expensive material, the Sapphire glass being used is actually a synthetic sapphire much like zirconia is to diamond. Sapphire glass is also noted as being only second to diamond in terms of hardness and is commonly used in shatter resistant windows in armored vehicles and in the video below, it has been fitted to an Apple iPhone and then scraped with a rough concrete block. Check it out for yourself below and petition your favourite smartphone maker for it as Apple is already rumoured to be doing so for the next Apple iPhone 6.
