Northstar Onyx Odd Quality Rods
Odd quality glass is first quality glass that is out of round, thinner/thicker than normal, has a taper, varies in diameter, and/or not full length.
Onyx is the smoothest most saturated black in the Northstar palette. It is well suited for stringer applications and blown work. It is a green based black and in certain lights it has a slight green tint. Onyx can be worked hot and long without boiling issues and it is not sensitive to reduction. For best results keep it in a neutral flame. It looks great as a backing for NS-13 Amber/Purple and by itself. It is great for backing dichroic, gold, and silver fume. For additional information about NS-76 Onyx refer to Northstar Newsletter issue 13.
