Midnight - Northstar
Midnight is a deep fully opaque blue. It is great for stringers and thin cane work and can be stretched out far! It is heat and flame sensitive. It must be warmed up slowly and once glowing heat gently. Because the color is so intense it must worked in an oxidizing flame. If the flame is not oxidizing enough, the color will develop grayish brown streaks.
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.
