Scientists have produced an oxide glass with unprecedented toughness. Under high pressures and temperatures, they succeeded in paracrystallizing an aluminosilicate glass: The resulting crystal-like structures cause the glass to withstand very high stresses and are retained under ambient conditions.
…and with those steps are even more potential points of failure. This is why we shouldn’t get too excited.
It’s promising and I hope it works out, but we should temper our expectations.
