The Difference Between Clear & Low Iron Glass

Introduction

Clear glass and low iron glass are two commonly used materials, but they serve different purposes. Have you ever wondered how a slight difference in composition can change a glass's appearance? In this article, we’ll explore the key differences between clear and low iron glass. You'll learn which type of glass is best for your design or construction needs, and why choosing the right one can significantly impact the final result. Whether you're working on a budget-friendly project or a high-end design, this guide will help you make the right decision.

What is Clear Glass?

Composition of Clear Glass

Clear glass is made from raw materials like silica sand, soda ash, and limestone, all of which naturally contain iron. The iron present in these materials is responsible for the slight greenish tint in the glass, particularly noticeable at the edges or in thicker sheets. The higher the iron content, the more pronounced the green tint becomes. While subtle, this tint should be considered when aesthetics and color clarity are important.

Common Uses of Clear Glass

Clear glass is commonly used in everyday applications where the greenish tint is not a concern, such as:

● Residential windows

● Mirrors

● Cabinet inserts

● Budget-conscious projects where clarity isn't critical

What is Low Iron Glass?

Composition of Low Iron Glass

Low iron glass, also called extra-clear or ultra-clear glass, has significantly reduced iron content, giving it a crystal-clear appearance with no green tint. This reduction in iron ensures that the glass remains completely color-neutral, even in thicker sheets.

Low iron glass is typically used when the purity of color and light transmission are crucial, as it allows for the most accurate viewing of true colors, making it ideal for high-end applications where clarity matters.

Common Uses of Low Iron Glass

Low iron glass is often used for premium applications where transparency and clarity are essential, including:

● Frameless shower doors

● Display cases

● Luxury interiors

● Museum-quality installations

For projects requiring the highest level of clarity, REACH offers low iron glass options that provide unparalleled transparency. Whether you’re creating high-end retail displays or constructing luxurious glass walls, low iron glass delivers superior aesthetics, ensuring true color rendering and refined design.

Key Differences Between Clear and Low Iron Glass

Color Appearance

● Clear Glass: Clear glass has a slight greenish hue, particularly noticeable around the edges and more pronounced with thicker sheets. The green tint is a natural result of iron oxide content in the raw materials.

● Low Iron Glass: Low iron glass is crystal-clear, with no greenish tint, offering true color accuracy. It remains transparent even at thicker thicknesses, providing a purer, more vibrant appearance.

Light Transmission

● Clear Glass: Clear glass transmits around 83-86% of visible light, though this can be muted slightly due to the iron content.

● Low Iron Glass: Low iron glass offers enhanced light transmission of 90-91%, resulting in brighter and more vibrant spaces, making it ideal for applications where maximum brightness and color accuracy are critical.

Edge Color

● Clear Glass: The edges of clear glass are often noticeably green, especially in thicker panels. This can detract from the overall clean look, particularly in applications where edge visibility is prominent.

● Low Iron Glass: Low iron glass features bluish or completely transparent edges, which provides a cleaner, more modern appearance and a refined look.

Durability & Strength

● Both clear and low iron glass can be tempered or laminated to meet safety standards and enhance durability.

● Clear Glass: Clear glass tends to hide small flaws or scratches due to its greenish tint, which can sometimes mask imperfections.

● Low Iron Glass: While low iron glass is equally strong, it may show scratches or fingerprints more easily due to its higher transparency. It requires extra care during handling and cleaning, especially in high-traffic areas.

Low iron glass offers superior clarity and light transmission, making it the ideal choice for projects where aesthetics and brightness are crucial. On the other hand, clear glass provides a more budget-friendly solution while still offering reliable functionality in many standard applications.

When to Choose Clear Glass vs. Low Iron Glass

Best Applications for Clear Glass

Clear glass is an affordable, reliable choice for applications where a perfect color rendering isn’t required. It is ideal for:

● Budget-friendly projects where cost control is key

● Framed windows and mirrors where the green tint won’t be noticeable

● Cabinet glass or shelving where slight tint isn’t a concern

● Standard partitions or interior doors

For projects that need clear glass but don’t demand premium aesthetics, clear glass remains a practical and cost-effective option.

Best Applications for Low Iron Glass

Low iron glass is perfect for applications where color accuracy, light transmission, and visual appeal are essential. It works best in:

● Frameless glass showers that require a sleek, modern look

● Display cases or retail storefronts where products need to be showcased in the clearest possible glass

● Museums, galleries, and high-end interiors where transparency and true color representation are key

● Projects requiring color precision and clarity for aesthetic purposes

For high-end installations, REACH’s low iron glass delivers superior clarity and transparency, ensuring luxury designs maintain a pristine look.
