The color can produce pale yellows to ambers to a deep purple. To yield the most vibrant purples, work in a hot neutral to slightly oxidizing flame. Reduction will affect the strike. Try encasing your favorite Amber/Purple with NS-032 Violet, or NS-031 Lavender. To enhance NS-013 Amber/Purple try backing it with NS-054 Star White. For a complete guide to working NS-013 Amber/Purple refer to the Northstar bead brochure and Northstar Newsletter issue 2.
