How East German Scientists Created Glass 15x Stronger Than Normal

Ever wonder how communist scientists accidentally created the world's most unbreakable drinking glasses? In 1977, East German researchers developed Superfest glass that was 15 times stronger than regular glass - but this revolutionary technology completely disappeared when the Berlin Wall fell. Daniel Torres investigates one of the Cold War's strangest scientific mysteries. On Proof Positive, we uncover how East Germany's ion exchange process created glass so tough it could survive 15,000 wash cycles compared to normal glass's measly 1,000. You'll learn why this "super glass" took 20 hours per batch to make, how it got exported to over 30 countries (including Western nations), and why a...
