Northstar Borosilicate Coloured Rods & Frit

Northstar Boro Nile Full Rod

Nile First

NS-089 Nile is a unique organic version of our NS-013 Amber/Purple. It yields rich earthy tones and burnt amber hues. It is well suited for blown and sculptural applications, but it is not saturated enough for thin stringer applications. It is also useful as an overlay colour. When working NS-089 Nile use a hot oxidizing flame. It can be flame or kiln struck to yield a rich “glazed pottery-like” finish. It is also interesting to note that when this colour is coiled, the coil lines are virtually unnoticeable and it yields a truly uniform surface. Be sure to try it over you favorite opaque.

Its most exciting application is as an overlay colour. It looks amazing over NS-081 Blue Caramel

Nortstar Boro Purple Urple Full Rod

Purple Urple First,

NS-101 Purple Urple is a dark purple that looks like NS-80 Hyacinth but works differently in the flame. This opaque purple uses chrome based technology but does not have cracking problems. It is great for blown work and thin stringer application. It is heat and flame sensitive so it must be heated up slowly to prevent boiling. Once it glows red, NS-101 Purple Urple will take heat well. Because of its intensity it is sensitive to reduction. If the flame is not oxidizing enough, grey and brown streaks will develop on the surface of the glass. Try it with a layer of NS-32 Violet for a deep purple effect.

Northstar Boro Double Amber Purple Full Rod

Double Amber Purple First,

NS-026 Double Amber/Purple is the more intense version of NS-013 Amber/Purple. It produces the most exciting metallic purples and vermilions.

Double Amber/Purple can be stretched further and can be blown relatively thin without losing the vibrant purple strike. Be sure to try layering Double Amber/Purple over NS-081 Blue Caramel.
