Low-iron glass, also known as extra-clear glass or optically clear glass, is produced by reducing the amount of iron in the molten glass formula.

This type is more transparent than regular glass, and doesn’t have that greenish tint, increasing the light transparency by 5 to 6 percent.

“Due to its composition, low-iron glass can transmit up to 91 percent of light compared to the 83 percent associated with conventional clear glass, allowing it to be used in a variety of different applications.”

Since the edgework of low-iron glass is clearer and less green than clear glass, it’s not just great for color matching—it is also great to use for display cases and shelves in retail stores.
