How Float Glass is made

The Float Glass Process was invented in 1952 by Sir Alastair Pilkington, a british engineer and businessman who perfected the process for commercial manufacture. The name comes from the process of Float Glass production which involves floating molten glass on a bed of molten metal and allowing it to form using a combination of gravity, weight, temperature and the actual amount of glass used. This method allows for uniform thickness and flatness and is vastly superior to previous methods of glassworks manufacture.

Float Glass uses

Today, float glass is the most widely used form of glass in consumer products. Due to both its high quality with no additional polishing required and its structural flexibility during production, it can easily be shaped and bent into a variety of forms while in a heated, syrupy state. This makes it ideal for a variety of applications such as

  • Automobile glass (e.g. windshields, windows, mirrors)
  • Mirrors
  • Furniture (e.g. in tables and shelves)
  • Insulated glass
  • Windows and doors

Most forms of specialised glass are a result of standard float glass that has been further processed to achieve different characteristics, these include:

  • Toughened glass
  • Decorative Glass
  • Frosted glass
  • laminated glass
  • Soundproof glass

Float Glass vs Plate Glass

Before the process of Float Glass was perfected, Plate Glass was the dominant standard in glass manufacture up until the 1960’s. Unlike float glass,the process methods used in Plate Glass cause far more imperfections such as warping, bubbles and scratches. It’s worth noting that Plate Glass produced prior to 1920 was also most likely hand made making it unique and in turn, quite valuable.
