Jet Black First,

NS-125 Jet Black is a very dense black. It is well suited for sculptural applications and blown work. It is creamy and works easily, making it a welcome addition to the palette of blacks from which to choose. When working NS-125 Jet Black, do so in an oxidizing flame. If worked in a reductive environment it will develop grey streaks on the surface and result in a dull matte finish. When applying the colour, do so gently. After it is melted in it can take a lot of heat. NS-125 Jet Black is great in combination with many colours and serves as a background for striking colours.

Northstar Boro Purple Lilac Full Rod

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.

Northstar Boro Plum Krazy Full Rod

Plum Krazy First,

NS-093 Plum Krazy is a dark transparent faux purple that strikes to a rich smoky blue. Work in a cool oxidizing flame to prevent overheating and striking the colour. When ready to strike, either kiln at 1050F or bathe the glass in a gentle bushy neutral flame to bring out the soft blue strike. This colour is best suited for moderately thick coil-potted blown work and sculptural applications. When encased in clear this colour produces a vibrant violet with wisps of metallic blue. Be sure to try it over NS-054 Star White or NS-081 Blue Caramel. Prolonged reduction leads to a greyish blue opaque surface.
