Northstar-24 Transparent Green is a transparent emerald green. It is intense enough for blown work and looks great in sculpture. NS-24 is sensitive to atmosphere and in order to maintain its original color, work in an oxidizing flame. If worked in a reducing flame, NS-24 will develop brick red streaks. Try layering Transparent Green over NS-53 Forest Green or NS-27 Green Exotic for exciting effects. Refer to Northstar Newsletter issue 6 under the heading ‘The Importance of Oxidation’ for additional information.
