Lava - ODDS - Northstar
Lava is a bright intense opaque orange. It is very bright and well suited for stringer application and blown work. It is not terribly sensitive to flame chemistry but stay out of overly reducing flames. Lava, however, is heat sensitive so it must be worked carefully to prevent boiling. Encasing with clear is another method to shielding the color, but not necessary. Lava can be easily worked on the surface and will not boil or scar if worked carefully in a soft flame. A nice color effect to try is a layer of NS007 Ruby over NS064 Lava.
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.
