Northstar Onyx (76) - Fore Powder 1 lb. (70/100 Grade Mix) Frit Fore Powder 16 oz jar
Onyx is the smoothest most saturated black in the Norsthar 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.
