Low-Iron Glass vs. Standard Clear Glass

Leave a Comment

The differences between low-iron and traditional clear glass are pronounced enough that many people can’t believe what they’re seeing – or what they haven’t been – when they’re shown low-iron glass options. Traditional clear glass can be hazy and is often faintly tinted, even at its best. Color issues may arise on the edges of […]

Understanding the Refractive Index of Glass

Leave a Comment

Understanding the behavior of light can be an important factor when determining which glass materials to use for your manufacturing process. When light passes through a substance, it decreases in velocity. This is manifested by an increase in the substance’s refractive index. Much can be learned about the optical properties of a glass material by […]

Understanding Optical Glass Surface Specifications

Leave a Comment

To ensure the manufacture of consistently high-quality, high-performance glass components and products, it’s critical to utilize optical specifications. These are useful in two ways: First, they establish an acceptable standard by which a glass surface must perform; second, they can help determine the amount of time, money, and labor that should be spent on the […]

Material of the Month: Borosilicate

Leave a Comment

In the late 19th century, a German glassmaker by the name of Otto Schott developed what was then a revolutionary new type of glass: It included boric oxide, differentiating the product from the soda-lime-based glass products on the market. This unique material became known as borosilicate glass or, simply, boro glass. Borosilicate can be used […]
