*What Color is Glacier Ice?
The ice we see in daily life is mostly clear and colorless. As a child, whenever I saw the pale blue ice sculptures in aquariums, I thought they looked unrealistic. Little did I know, I was wrong. While traveling in Scandinavia, I visited a glacier in Norway, and to my surprise, its ice was the same pale blue color Iâd seen in aquariums. This shade, known as âglacier blue,â is a natural phenomenon. Regular ice appears white because it contains air, scattering light in all directions. Glacier ice, however, forms over centuries of compressed snow, which removes air and increases clarity. Pure ice absorbs more red light, reflecting blue light and making the ice appear bluish to our eyes. In the end, the aquarium displays were right, and I was mistaken. This experience reminded me of the importance of firsthand encounters to truly understand the world around us.
