Periwinkle - Northstar
Periwinkle is a fully opaque baby blue that is great for blown work, and stringer application. To prevent any boiling issues, heat NS055 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 NS019 Light Cobalt over NS055 Periwinkle for bright neon blue. Also be sure to try layering NS014 Irrid over NS055 Periwinkle.
Second quality glass can have the properties of odd quality glass, but may also have small stones, air bubbles, vary in tone/shade, or the shape can be very out of round. Both odd and second quality glass can provide a great value to the right person.
