What are the Benefits of Low Iron Soda Lime Glass?

Low Iron Soda-Lime Glass or water-white glass is a clear transparent soda-lime-based glass that is almost tint-free, resulting from its being produced from higher quality grades of silica sand that are almost totally free of iron oxides. 1/8” thick low iron glass transmits approximately 2 to 3% more light than regular soda-lime glass, making it a perfect solution for applications requiring maximum visible light transmission and little to no color distortion.

Low Iron vs. Regular Soda Lime GlassFeatures

  • 2 to 3% higher light transmission in 1/8” thickness vs. regular soda-lime glass and 8% higher light transmission in ½” thickness vs. regular soda-lime glass
  • 91% visible light transmission for 1/8” – 3/8” thick glass
  • Good flatness and surface quality due to float process
  • Can be coated with anti-reflection coating on both sides to achieve 98% total light transmission
  • Retains colorlessness and clarity over time unlike some plastic components which can yellow
  • Can be fully heat tempered to increase thermal shock resistance and mechanical strength
