Northstar Onyx is the smoothest, most saturated black in the Northstar palette. It is well suited for stringers 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 Northstar Amber/Purple and by itself. It is great for backing dichroic, gold, and silver fume.
Size: Diameter 5-7mm, length 20", weight per rod .07 lb. All Northstar rods are first quality.
Due to the weight and length of the rods you may receive .30 pound vs .25 pound (as an example) when ordering. This will cause the cost to rise and the amount you expect to pay for your glass may change.
If this is a problem, please let us know and we will “underweigh” your glass. This means instead of .25 pound you may receive .20 to .22 pound. Please be aware that it is almost impossible to pull exactly .25 pound. We will always try our best to get as close as possible to the weight that is ordered, but due to the factors stated, these weights may substantially increase the total cost of your order.
