Periwinkle is a fully opaque baby blue that is great for blown work, and stringer application. To prevent any boiling issues, heat C3-55 Periwinkle slowly and gently. Once the color is glowing it can take a lot of heat. The trick is patience with a soft flame! Periwinkle is sensitive to atmosphere, and must be worked in a soft neutral to oxidizing flame. Try layering C3-19 Light Cobalt over NS-55 Periwinkle for bright neon blue. Also be sure to try layering C3-14 Irrid over C3-55 Periwinkle. For additional information about C3-55 Periwinkle refer to Northstar Newsletter issue 15.
