The Unbreakable Glass

 The Superfest

Glass—the discovery that revolutionized the whole world in many ways. Nowadays, our homes to jewelry many things consist of glass to some extent. But have you ever wondered about unbreakable glass (literally)? During the 1980s, East Germany created an unbreakable glass by a chemically strengthening process. The purpose for creating the glass is to maximize the glass's life because the raw materials for making the glass were scarcely available in the country. Due to its unbreakable nature, it was the first choice for the customers as a one-time investment. Fast-food shops, pubs, and cafes were the main customers of the glasses. Soon, the glasses became popular all over Europe and the company expanded its product range by including ice-cream glasses, vases, coffee mugs, etc.

 

But as the law of nature says, everything positive comes with negativity. Same happened with the 'Superfest'; the unbreakable nature of the glasses lowered the profit margin exponentially as the customers were purchasing the glasses for only one time, as they would last for decades. As a result, the production unit shut down in 1990, and the 'Unbreakable Glasses' became a piece of history. Today they are highly valued collectibles because of their legacy, rarity, and historical importance. They are considered an innovation in the modern field of glass engineering.
