SCHOTT celebrates 20th birthday of the special technical glass BOROFLOAT®

World’s first production line for floated borosilicate glass went into operation in Jena, Germany in 1993, creating a successful product with a broad range of applications.

The international technology group SCHOTT is celebrating a milestone anniversary: The 20th birthday of the world's first microfloat facility for manufacturing floated borosilicate glass, which was put into operation on November 2, 1993.The high-tech glass BOROFLOAT® is used all over the world in a wide range of applications, including fire-resistant glazing, safety glazing for armored limousines, lighting technology, internal panes for pyrolysis ovens, and optical filters.

“Borosilicate glass is one of the main pillars for the SCHOTT site in Jena. It helps to secure the future of our site,” said Dr. Lutz Wehmeier, Managing Director of SCHOTT Technical Glass Solutions GmbH. Manufacturing high-quality, floated borosilicate glass is made possible not only by our unique knowledge of high-temperature melting and forming processes, but also by using special raw ingredients.

Today, this specialty glass product is known around the world and put to use in many different industries. Thanks to its myriad characteristics, like resistance to extreme temperatures, high mechanical load-bearing capacity, excellent surface quality, and outstanding optical properties, it is ideally suited for use in a wide variety of different applications.

The curved vehicle protection product SCHOTT RESISTAN® is manufactured using Borofloat®, a technical borosilicate glass offered by SCHOTT. A quarter of the weight can be saved by using this special material instead of normal glass.

“BOROFLOAT® borosilicate glass is truly multitalented. We have developed a great deal of application-specific expertise over the last 20 years and provide extensive customer support,” explained Thomas Kloss in reference to the company's recipe for success. The sales manager for BOROFLOAT® glass has been with the company since the product was first introduced. “I can still remember when we put our first tank into operation and began manufacturing this product,” added Kloss.

Background information:

With float technology, the liquid glass floats as a continuous ribbon on molten tin. What is unique about this process is that there is no need to grind the glass because it takes on an extremely smooth, mirror-like surface.
