Northstar Unobtainium Full Rod

NS-104 Unobtainium is a very dense gun metal blue with lots of sparkle. It is well suited for stringer application and blown work. It is easily worked and can take a lot of heat. To keep the colour most vibrant, work in a neutral to slightly oxidizing flame. Try to avoid deep encasement, it may cause cracking. Please use NS-104 Unobtainium with care and test your application before making expensive pieces. Outside work seems to work just great with no problems. Try coating NS-104 Unobtainium with NS-86 Garnet or NS-88 Pomegranate to achieve a brilliant ruby sparkle. Any transparent colour coated over NS-104 Unobtainium looks great.

Northstar Silver Unobtainium

NS-120 Silver Unobtainium is also a dark blue sparkle that has silver in it. It is well suited for stringer application and blown work. It is easily worked and can take a lot of heat. To keep the colour most vibrant, work in a neutral to slightly oxidizing flame. Try to avoid deep encasement that may cause cracking. When worked in an oxidizing flame NS-120 Silver Unobtainium stays a dark blue colour with wispy hues of silver over it. If reduced the colour does not show much sparkle but still has many vivid colours.

Northstar Dark Amethyst Full Rod

NS-106 Dark Amethyst is a light transparent violet colour. This is a “what you see is what you get” colour. Use in a slightly neutral to oxidizing flame for best results.

Stringers tend to lose colour and may appear as a clear Violet

Northstar Boro Ursa 50grm

Ursa First

NS-140 Ursa is a response to our artists who have been asking for an opaque brown. We have experimented with the alternatives to the industry standard cadmium based brown.We have formulated Ursa with a good working viscosity , as well as dense colour saturation to help the artists explore this earth tone. As with many opaque colours this glass can suffer from boiling issues if pushed too fast or hot.

Northstar Boro Turquesa Full Rod

NS-020 Dark Cobalt is the second most saturated of the four shades of cobalt blue Northstar produces. Dark Cobalt is well suited for thin blown work and cane work. Because of its intensity it must be worked in an oxidizing flame to prevent greying.

Northstar Boro Turbo Cobalt Full Rod

Turbo Cobalt First,

NS-033 Turbo Cobalt is the most intense cobalt blue in the Northstar palette. It is great for stringer application, and stretching out thin. If kept moderately thick, Turbo Cobalt is an excellent faux black. Because of its intensity, NS-033 Turbo Cobalt must be worked in a highly oxidizing flame to prevent greying. If however you are looking for a battleship grey, it can be achieved by working Turbo Cobalt in a heavily reducing flame. For a nice colour combination try layering NS-026 Double Amber/Purple over NS-033 Turbo Cobalt.

Northstar Boro Transparent Green Full Rod

NS-024 Transparent Green is a transparent emerald green. It is intense enough for blown work and looks great in sculpture. NS-024 is sensitive to atmosphere and in order to maintain its original colour, work in an oxidizing flame. If worked in a reducing flame, NS-024 will develop brick red streaks. Try layering Transparent Green over NS-053 Forest Green or NS-027 Green Exotic for exciting effects. Refer to Northstar Newsletter issue 6 under the heading ‘The Importance of Oxidation’ for additional information.

Northstar Boro Tan Silver Creek Full Rod

Tan Silver Creek First,

NS-114 Tan Silver Creek is a yellowish cream colour. It can yield rich purplish blue and creamy tan tones. When kept in a more oxidizing environment, you will get more of the blues and purples. If reduced, a silvery haze will appear on the surface. NS-114 Tan Silver Creek is easy to work and can take a lot of heat which makes it a forgiving striking colour. It can be stretched out and is good for blown work and sculpture. If you are looking for something even more intense, try NS-44 Caramel or NS-102 Silver Bullet.

Northstar Boro Sublime Full Rod

NS-066 Sublime is a transparent iridescent signal light green. It is the most eye catching borosilicate transparent colour in the palette. Sublime is atmospherically stable meaning it can be worked in any flame without the colour being affected. It is a member of the transparent family but it is saturated enough for thin blown work. Its most exciting application is as an overlay colour. It looks amazing over NS-081 Blue Caramel

Northstar Boro Star White Small Frit

Northstar Boro Frit, Star White

Northstar Boro Star White Full Rod

Star White First,

NS-054 Star White is a creamy fully opaque white. It is an indispensable colour in the palette for all applications. It is great for sculpture, stringers, blown work, and backings for all transparent colours. With several reformulations Star White has been turned into an easy colour to work. It is atmospherically stable meaning it can be worked in any flame without the colour being affected. To prevent any boiling issues, heat NS-054 Star White slowly and gently. Once the colour is glowing it can take a lot of heat. The trick is patience with a soft flame!

Northstar Boro Star White Fine Frit

Northstar Boro Frit, Star White

Northstar Boro Skyline Full Rod

 Skyline First,

NS-083 Skyline is a fully opaque bright baby blue. It is well suited for stringer applications and blown work. It is not sensitive to reduction but must be heated up slowly to prevent boiling. Once the colour is glowing it will take a lot of heat. Skyline is also a great background colour for many transparent colours.
