Northstar Borosilicate Coloured Rods & Frit

Northstar Boro Turbo Cobalt 50grm

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 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.

Mauvelous First

NS-142 Mauvelous also derived from our attempts at earth tones formulated without using cadmium metals as colourant.We are happy to present this beautiful mauve colour to our artists as a tool to explore creativity. As with many opaque colours this glass can suffer from boiling issues if poushed too fast or hot, so let the heat sink in for best working results.

Northstar Boro Lucy 50grm

Lucy, the newest colour to make it into production at Northstar glass is ready to roll! This colour works best in oxidizing and neutral flames.

Lucy is clear with very few air inclusions, and when worked it remains quite clear in normal lighting. Under uv lighting Lucy is a very intense hot pink!  A very stable colour to add to the uv pallet.  Lucy works great on the surface and can also be worked under clear.  Fantastic for blown and sculpted applications.  My favourite use of Lucy, is layering it over all other colours to create unique blends! 

Northstar Boro Rootbeer 50grm

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.

Northstar Boro Orange 50grm

NS-005 Orange is a bright transparent striking orange that is well suited for sculpture, bead work and moderately thin blown work. The striking process is temperature related but in order to prevent any muddying, work in a neutral to slightly oxidizing flame. It is recommended to kiln strike NS-005 Orange. NS-005 Orange looks great over NS-54 Star White, and be sure to try layering NS-13 Amber/Purple over it.

Northstar Boro Blue Caramel 50grm

A rich buttery striking color. Keep it oxidized for hazy blues and greens. Reduce for the most scintillating mirror-like sheen.

Northstar Boro ill-Uminati 50grm

iLL-Uminati First,

This glass contains URANIUM so it will fluoresce under UV light. We have found that short wave UV light in 365nm-405nm works best. We feel this colour has amazing working properties and can be used in any type of flame. This glass can be used in any application with no problems of cracking or incompatibility. The colour in natural light is an amazing transparent neon green with many opportunities for layering. If you are cold working use standard safety practices regarding personal protection. Please follow the link for radiation reading from OSU Radiation Centre.

Northstar Boro Silver Unobtainium 50grm

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 Boro Mystery Aventurine 50grm

NS-078 Mystery Aventurine is a brilliant aventurine colour that strikes to deep purples and reds. When thinned it turns a pale yellowish amber. Mystery Aventurine is well suited for blown work and stringer application. It is not overly sensitive to reduction and is best worked in a hot neutral flame. For the best strike, kiln striking is the way to go. When using this colour heavily encased keep work time to a minimum and kiln anneal thoroughly. Mystery Aventurine looks great over NS-076 Onyx and NS-054 Star White.

Northstar Boro Turquesa 50grm

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 graying.

Northstar Boro Sublime 50grm

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
NEW

Northstar Boro Bubblegum 50grm

NS-062 Bubblegum is a fully opaque flamingo pink. It is atmospherically stable so it can be worked in any flame without the colour being affected. It is flame sensitive so heat it gently in a soft flame. Once it is heated Bubblegum will take a lot of heat without any boiling issues. Bubblegum is a great backing colour and well suited for sculpture. Try it as a backing for NS-013 Amber/Purple, or NS-026 Double Amber/Purple. It is also a great backing for gold fume.

Northstar Boro Pink 50grm

Pink First,

NS-023 Pink is a light transparent bright pink. It is atmospherically stable meaning it can be worked in any flame without the colour being changed. It is also resistant to excessive heat, and can take a lot of abuse. Because NS-023 Pink washes out when thinned, most regard this colour as one for solely sculpture. Surprisingly another great role for NS-023 Pink and other transparent colours is use as overlay colours. NS-023 Pink looks great over NS-026 Double Amber/Purple, NS-045 Blue Moon, and many others. By using even a thin coating of Pink, a striking colour can be transformed into an entirely new shade.

Northstar Boro Purple Lilac 50grm

Purple Lilac First,

We recommend using this colour in any type of flame. For a more opaque colour use a slightly reducing flame and for beautiful transparent colour use an oxidizing flame. This colour can be used in any application without problems as well. We consider this colour to be a striking colour so the more you anneal it the more opaque it will turn. Please remember that if you thin out the colour too much you will not be able to bring it back to a nice opaque colour.
