Another great use for NS-025 Peach is use as an overlay colour, as with any other transparent colour. NS-025 Peach looks great over NS-26 Double Amber/Purple, as well as NS-044 Caramel.

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.

Northstar Boro Rust Full Rod

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.

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

Goldenrod First,

NS-084 Goldenrod is a bright, saturated intense opaque dark yellow. It is well suited for stringer application and thin blown work. It is not terribly sensitive to flame chemistry but stay out of overly reducing flames. Goldenrod however is heat sensitive so it must be worked carefully to prevent boiling. Encasing with clear is another method to shielding the colour, but not necessary. Canary can be easily worked on the surface and will not boil or scar if worked carefully in a soft flame. For a nice colour effect layer NS-013 Amber/Purple over NS-084 Goldenrod.

Northstar Boro Cherry Full Rod

Cherry First,

NS-065 Cherry is the most eye-catching member of the intense opaque family. It is a bright candy apple red that is well suited for stringer application and blown work. Cherry is slightly sensitive to reduction, so work in a soft neutral flame. Cherry is however heat sensitive so it must be worked carefully to prevent boiling. Encasing with clear is another method to shielding the colour, but not necessary. Cherry can be easily worked on the surface and will not boil or scar if worked carefully in a soft flame. A nice colour effect to try is a layer of NS-037 Rootbeer over NS-065 Cherry.

Northstar Boro Mystery Aventurine Full Rod

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 Ruby Odd 50grm

NS-007 Ruby is a medium intensity striking ruby. It is good for most blown work and can be worked relatively thin without washing out. Because it is more saturated, NS-007 Ruby must be worked in a moderately oxidizing flame to prevent muddying or liveriness. To strike NS-007 Ruby, a kiln is recommended. For a great colour combination, try layering NS-009 Yellow over NS-007 Ruby. For extra brilliance, back the ruby with an opaque such as NS-044 Caramel or NS-062 Bubblegum
