The Unbreakable Glass That Vanished: The Mystery of Zupa Fest

TLDRZupa Fest, an unbreakable glass invented in East Germany in 1975, was nearly 15 times more durable than ordinary glassware. However, despite its undeniable quality, it failed to find a market and hasn't been produced for over four decades. The glassware, made stronger through a process called ion exchange, was ahead of its time and faced competition from similar products in the US. Today, collectors hoard the remaining Zupa Fest glasses, while planned obsolescence remains a dominant business model.

Q&A

What is Zupa Fest?

—Zupa Fest is a type of glassware invented in East Germany in 1975. It is known for being nearly 15 times more durable than ordinary glassware.

How was Zupa Fest made so strong?

—Zupa Fest was made stronger through a process called ion exchange, which involved bathing the glass in a potassium nitrate solution to create tension and prevent cracks.

Why did Zupa Fest fail to find a market?

—Zupa Fest faced challenges in finding a market due to competition from other glassware and a business model that favored planned obsolescence.

Was Zupa Fest the only glassware of its kind?

—No, Corning Glass in the US independently developed similar glassware using the same process of ion exchange.

What happened to Zupa Fest?

—Zupa Fest hasn't been produced for over four decades and is now a collector's item. However, some restaurants and bars in Eastern Germany still use the remaining glasses.
