Brillo - SECONDS - Northstar
Northstar's Brillo can produce sparkling colors when mixed with any transparent color. Work in a hot neutral to slightly oxidizing flame to yield the most even color.
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.
