What is Low Iron Glass?

Low iron glass, often known as extra-clear or ultra-clear glass, is a type of glass with lower iron content compared to standard ‘clear glass’. In most types of glass, iron naturally occurs in the base materials, imparting a greenish tint to the glass when it is thicker or viewed from certain angles.

The glass is manufactured by either using raw materials with reduced iron content or by removing iron impurities during the glass-making process. This results in glass that is clearer and more transparent, allowing greater transmission of natural light through the glazing design without the typical greenish tint associated with conventional ‘clear glass’.

This glass is the preferred option for applications where colour accuracy and optical clarity are paramount. It finds frequent use in architectural projects requiring high levels of transparency, such as structural glass windows, glass facades, and exhibition cases. Additionally, it is employed in solar panels, aquariums, photographic equipment, and other situations where maintaining an object’s true colour and clarity is essential.
