Looks like this may become a reality very soon.
The glass contains aluminum oxide compounds, which are well known for their toughness.
Glass is based on silica (silicon dioxide), which is the main component of sand.
When mixed with silicon dioxide, it results in an exceptionally safe, tough and indestructible glass.
The Japanese team manufactured their glass without a container to avoid the formation of any pesky crystals.
The glass underwent hardness, strength, and elasticity tests including Youngs modulus and Vickers methods.
We are looking to commercialise the technique within five years.
