Low Iron Glass vs Clear Glass

What is Low Iron Glass?

Low iron glass is glass made from a special silica sand that has naturally lower iron levels than that of clear glass. It’s this lower iron content that provides the colour neutrality and all but eradicates the greenish tint that’s found in clear glass.

Low iron glass and clear glass are two types of glass with distinct characteristics, primarily related to their clarity and light transmission. Let's explore the key differences between low iron glass and clear glass:

**1. Iron Content:

  • Low Iron Glass: Low iron glass is manufactured with reduced iron content compared to standard clear glass. The low iron content enhances the glass's transparency and clarity, allowing more light to pass through without the greenish tint that is characteristic of standard clear glass.

  • Clear Glass: Clear glass, while generally transparent, contains a higher level of iron impurities compared to low iron glass. This can result in a slight greenish or bluish tint, especially noticeable in thicker or larger panels.

**2. Color and Clarity:

  • Low Iron Glass: Low iron glass is virtually colorless and offers exceptional clarity. This makes it an ideal choice when a neutral appearance and maximum light transmission are desired, such as in applications like display cases, aquariums, high-end windows, and architectural projects.

  • Clear Glass: Clear glass can have a subtle green tint due to the presence of iron, particularly noticeable in thicker or larger pieces. This tint may affect the color accuracy of objects viewed through the glass.

**3. Light Transmission:

  • Low Iron Glass: Low iron glass allows more light to pass through without distortion, making it suitable for applications where optimal clarity and true color representation are crucial.

  • Clear Glass: Clear glass allows light transmission but may slightly alter the color of the transmitted light due to the iron impurities.

**4. Applications:

  • Low Iron Glass: Due to its high clarity and true color representation, low iron glass is often used in applications where aesthetics and visibility are critical, such as in storefronts, display cases, solar panels, and high-end residential and commercial architecture.

  • Clear Glass: Clear glass is widely used in various applications, including windows, doors, glassware, and everyday household items. However, its slight tint may limit its use in applications requiring exceptional clarity.

**5. Cost:

  • Low Iron Glass: Low iron glass is typically more expensive than standard clear glass due to the additional manufacturing process needed to reduce iron content and enhance clarity.

  • Clear Glass: Clear glass is generally more cost-effective than low iron glass.

In summary, the choice between low iron glass and clear glass depends on the specific requirements of the application. Low iron glass is preferred when maximum clarity, true color representation, and minimal tint are essential, while clear glass may be suitable for applications where a slight tint is acceptable, and cost is a factor.
