NS-72 Glacier Blue is a darker version of NS-70 Ice Blue. It has a green tint to the color and like NS-70 Ice Blue; Glacier adds great optical depth even in thin layers. It is not suitable for stringers or cane work, but it is great for sculpture and blown work. Its effect as an overlay color is impressive. Try this color over NS-55 Periwinkle or NS-83 Skyline for great color effects. As like NS-70 Ice Blue, Glacier is also sensitive to a reductive flame. Because it is more saturated, extra care has to be taken to prevent reduction from developing. By using a strong oxidizing flame no reddish brown streaks will develop.
