Northstar Boro Amber/Purple Full Rod

NS-026 Double Amber/Purple is the more intense version of NS-013 Amber/Purple. It produces the most exciting metallic purples and vermilions. It behaves similarly in the flame as regular Amber/Purple but because of its greater intensity more care has to be taken to prevent reduction.

125grm of Northstar Turquesa

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.

125grm of Northstar Turbo Cobalt

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.

125grm of Northstar Transparent Green

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.

125grm of Northstar Tan Silver Creek

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.

125grm of Northstar Sublime

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

125grm of Northstar Star White

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!

125grm of Northstar Skyline

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.

125grm Northstar Silver Unobtainium Odd

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.

125grm of Northstar Silver Creek

Silver Creek First,

NS-105 Silver Creek is a silver based colour which produces the most exciting metallic purples and vermilions as well as silvery greens and blues. It is a very stable colour. It behaves similarly in the flame as NS-13 Amber Purple and NS-26 Double Amber Purple, but because of its greater core range, more care has to be taken to prevent reduction and boiling. NS-105 Silver Creek can be stretched and can be blown relatively thin without losing the vibrant colours. Try using with other colours to achieve multi layered colour combinations.

125grm of Northstar Silver Bullet

NS-102 Silver Bullet is a look alike of NS-44 Caramel. It is a rich silvery tan color that can be stretched out thin. It is great for stringer application and blown work. Work in a hot neutral to oxidizing flame for bright tan colors. To bring out the silvery mirror like sheen, bathe the piece in a reducing flame. Try NS-07 Ruby or NS-13 Amber Purple over NS-102 Silver Bullet.

125grm of Northstar Rust

Rust First,

NS-043 Rust is a fully opaque striking ruby. It can yield a bright porcelain red, and rich earthy browns. Work Rust in a hot neutral to slightly oxidizing flame. It can be flame struck or kiln struck. It is well suited for sculpture as well as blown work. It is also useful as a backing for transparent striking colours.

125grm of Northstar Rootbeer

NS-037 Rootbeer is a striking red that can yield numerous effects ranging from rich blues and purples to reds and earthy browns. Rootbeer is well suited for sculpture and blown work of all thickness. It can be kiln or flame struck. It strikes more quickly than any other striking reds, so plan carefully. Work in a neutral to oxidizing flame to keep it from developing any liveliness. Try it with a backing of NS-065 Cherry.

125grm of Northstar Red Exotic

Red Exotic

NS-029 Red Exotic: The Exotic family contains the most saturated striking colours in the Northstar family. NS-029 Red Exotic produces a deep metallic burgundy. As with the other exotics work them in a super oxidizing environment until you are finished with the piece. Then, turn the flame down and bathe the piece in a super reducing flame for several second to produce the mirror like sheen. Another great effect that is possible with the Exotics is encasement with clear. This group of colours can be stretched out and is great for blown work. If heavily encased, be sure to anneal thoroughly. Exotics are also enhanced by a backing with NS-054 Star White. NS-029 Red Exotic differs from the rest in that kiln striking will amplify the red qualities. Try layering NS-023 Pink over Red Exotic
