Product Description

Onyx is the smoothest most saturated black in the Northstar palette. 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 NS13 Amber, Purple and by itself. It is great for backing dichroic, gold, and silver fume.
