Glass

Glass manufacturing, as with Steel and Ceramics, has a long-established process for manufacturing and quality control procedures.

Float glass is strengthened by immersing the product in nickel sulphide baths. This can result in nickel sulphide inclusions within the glass and depending on the size, these can subsequently cause catastrophic failure when exposure to pressure or heat. If this occurs when the glass is in situ, the results can lead to structural failures and even loss of life.

Traditional methods for quality control consist of stress testing the glass with heat until it explodes. This destroys potentially non-compromised glass and requires further firing of the product to remelt and remake – an energy-intensive process which is expensive, wasteful, and releases further carbon into the atmosphere. The exploding plate also causes considerable mess!

I3DR is using technologies developed through working with the Steel sector to identify, characterise and put in a 3D contextual map, defects within float glass.
