Now, scientists have developed a super-strong glass that mimics many of the properties of that fictional transparent aluminum.
That's why researchers have created a new type of glass that is stronger and tougher than steel.For now, the sample sizes are quite small, but the scientists figure to enlarge the size and work on making their discoveries marketable.
In fact, this new type of damage-tolerant glass has actually demonstrated a durability greater than any known material.
The new metallic glass is a microalloy that features palladium, a metal with a high "bulk-to-shear" stiffness ratio that counteracts the intrinsic brittleness of glassy materials.

Robert Richie is the materials scientist who led the Berkely contribution to the research. In a press release, he says the new glass is stronger than steel because "that glass undergoes extensive plasticity in response to stress, allowing it to bend rather than crack."
