Glass Glossary

Low iron glass is crafted using raw materials with a reduced iron content. This reduction in iron minimizes the inherent blue-green hue seen in standard glass, especially through the edges. As a result, it is the preferred choice for applications like shower doors, glass railings, and shelving where clarity and aesthetics are crucial.

Several sources of low iron materials originate from Europe, distant from major glass production facilities like Cardinal float glass factories, which play an integral role in the melting and processing of these materials.

In terms of light transmittance, low iron glass permits approximately 1 to 1½% more visible light to pass through than standard clear glass. The actual percentage can be affected if additional coatings such as LoĒ™ are incorporated.

Notably, Cardinal’s Purevision® is a premium example of low-iron glass. Boasting striking color accuracy and an alluring Icelandic blue edge, Purevision stands out with its almost colorless appearance and an impressive light transmittance of up to 91%, elevating the aesthetic potential of any application.
