Rods size: 5 -7 mm Length 51cm. Weight per rod  37grms. Approx. 12 - 15 rods per pound. NS-76 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. 

Working Tips:

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.
