NS-70 Ice Blue is a lush copper blue that has an unrivaled eye catching appeal. It is a light transparent color but it 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. When added over NS-45 Blue Moon, it produces a very appealing blue! To keep Ice Blue from dulling or discoloring, work in an oxidizing flame. If worked in a neutral to reducing flame the color will darken and develop reddish brown striations in the body of the glass. For additional information about NS-70 Ice Blue refer to Northstar Newsletter issue 10.
