NS-004 When worked in an oxidizing flame Dark Multi produces metallic blues and sea greens. When reduced, NS-004 Multi yields earthy reds and browns. Because it is more saturated it will react much more quickly to the particular chemistry of the flame. Due to the fact that it reacts more readily, do not over reduce. To yield other interesting effects, try encasing NS-004 Multi with clear or backing it with an opaque color. This color can be stretched thin, so it is well suited for delicate blown work, stringer application, or cane work.
