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.
Sounds like it exchanges rigidity for plasticity but it doesn’t have long term durability (once you damage the paracrystilline areas, they lose that property). Better than directional crystalline structures because there’s not a “grain”, but weaker.
