The Science of Low-Iron Glass: Why It Looks Clearer
Regular glass has a natural green tint from iron oxides. Low-iron glass reduces those impurities for crystal clarity, truer colours, and brighter interiors—especially noticeable in thicker panels.
Premium Look
More Light
Why Standard Glass Looks Green
Iron Oxides in Float Glass
Regular float glass contains iron oxides that absorb parts of the light spectrum, creating the familiar green hue—especially visible on the edges.
Thicker Panels, Stronger Tint
The thicker the glass (10mm+), the more pronounced the green. This can distort colours in back-painted glass or on displays.
What Makes Low-Iron Glass Different
Lower Iron Content
Manufactured with significantly reduced iron impurities for much clearer, neutral optics and minimal edge tint.
Higher Light Transmission
Brighter interiors with improved clarity—ideal where colour accuracy or a premium, “crystal” look matters.
Where Low-Iron Glass Shines

| Display cabinets & retail | Product colours appear accurate and vibrant |
| Table tops & shelving | Clearer edges and a premium, “crystal” aesthetic |
| Shower screens & partitions | Brighter, cleaner look in bathrooms and open spaces |
| Large architectural panels | Neutral clarity across tall/thick sheets |
