Low-iron glass is also referred to as “optically-clear” glass. It features superior, near-colorless clarity and brilliance. The visible light transmittance of low-iron glass can reach 92%, and depends on the quality of the glass, as well as thickness.

Low-iron glass is excellent for back-painted, color-fritted, and color-laminated glass applications, because it renders the truest colors.

Low-iron glass requires special production using raw materials with naturally low levels of iron oxide.
