Low Iron Glass vs Clear Glass: What’s the Difference

Comparison of standard glass and low-iron glass

Clear glass contains a relatively small amount of iron. This iron content is a natural occurrence from elements. While this is a natural process, it can lead to issues.

When comparing low iron and standard glass, the difference becomes clear. For applications like back-painting or applying specific colors, using regular clear glass can be challenging as it may be difficult to match the color accurately. This is where clear glass comes in. Additionally, for displaying delicate items like jewelry, the slight green tint in regular clear glass can distort the finer details. These types of glass can be used for glass balustrades, glass pool fences, glass partition walls, glass splashbacks and shower glass.

What is the difference?

Manufacturers produce extra-clear glass, by reducing the amount of iron in the molten glass formula. This type of glass is much more transparent than normal glass and lacks the greenish tint. In fact, altering the iron content can increase the average transparency by 5 to 6 percent.

Low-iron glass not only improves color matching but also enhances the flow of natural light when used in interior walls. According to Architectural Record, clear glass can transmit around 91% of light compared to 83% transmitted by conventional clear glass, making it suitable for various applications.

Due to its composition, clear glass allows for smoother back-painting or coating, ensuring the finished product matches the desired shade precisely. Architects and designers often choose clear glass for color matching and other applications where clarity is paramount.

While it’s not possible to have glass without any iron content (some level is necessary for production), the key is to have just enough to ensure durability without compromising clarity.
