Light Absorption in Liquid Contents and the Color of the Glass Research by Bradley E Sturgeon, PhD at Monmouth College in Illinois in 2008 showed that different colors of glass allow different levels of UV light into the bottle’s liquid.  He used both tungsten light and sunlight.  The sunlight contains high amounts of UV by nature. The tungsten much less. The results show that a clear glass protects the liquid inside from UV exposure 0%. Brown glass filters the largest amount of high energy light.  Green and especially blue are inefficient at filtering…continue reading →
