The NT colour line is by Unique Glass Colours come in powder form, are all non-toxic and food-safe (even the metallic colours). The NTs fire to rich, glossy, vibrant colour and are semi-opaque to opaque.
The NT line should be mixed with the UGC Medium (available separately - see the link below) to the consistency of melted ice cream and they fire semi-opaque to opaque when mixed on a 1:1 ratio. They can also be used in their dry form for stencilling or sifting techniques.
NT's were developed to be used on the top layer of float glass, but most fuse beautifully when fired between layers of glass. The photo shows the colour fired on top and when fused between layers. Note, that some of the colours, when fired in between glass, have a colour shift and some (like Mauve) actually turn white! Many different varieties of glass can be used with UGC colours.
We highly recommend testing to be assured of compatibility. Note: UGC colours can be used on the tinned and or non-tinned sides of float glass. If the colour pulls away from an area just use a wooden toothpick and rub over the area and the colour will flow into the area.
We recommend mixing 1/2 of a 1 oz. jar with UGC Medium, so you have powdered colour left in case you mix too thin or if you would like to use the powders for stencilling or other applications. The colours will settle in the jar so mix often during use. After being stored you will need to stir the colour FIRST before adding any liquid as our colours are all "thixotropic" meaning that the act of stirring will liquify the colour. If, after stirring, you still need them to be thinner you can add a bit more UGC Medium or water to bring them to the proper consistency.
Colours can be brushed, sponged, airbrushed or applied with the outline bottle. When spraying, proper equipment, including a mask is necessary. When using the "Puddle, push pull" technique, select a soft brush such as a 10/0 and fill to capacity, then allow colour to flow from the brush into the area to be coloured. If applied too thinly or pulled out too far it will appear streaky or washed out when fired. Wet colour, when viewed from underneath the glass should appear opaque. For a watercolour effect using the NTs you can wet the surface of the glass (with either UGC Medium or water) before applying the colour and then, applying them in an uneven manner, letting the colours run and blend into each other. You can spritz the colour with water to get it to run more or you can add more colour.
NTs can be mixed with each other but do test the colour you have mixed to be sure it is the result you want. Mixing any of the NT colors (not the Metallics) with Brite White or Vanilla will give you an almost unlimited range of gradated colour.
The four Metallic Colours in the range are White Diamond, Gold Dust, Copper Glow and Silver Sheen. The cooler these colours fire, the rougher the surface becomes. They also need to be used only on the top layer as fusing between layers takes away their metallic qualities.
Outline Black and Outline White come in liquid form and dry hard to allow colours to be brought right up to the line and fire to a matte finish
Average firing range is 1425F to 1550F (773°C to 843°C) but colours can be fired much hotter. We at UGC have taken the colours up to 1800F (983°C) and the colours remain stable. Firing on the cooler side will result in colours not being as shiny as when fired to the hotter temperatures.
The NT colours are perfect for artistic creations, commercial applications, in conjunction with stained glass techniques, used in teaching all types of studios.
NT colours can be used on the same piece along with the UGC Original and Artisan Colour lines, but the colour lines cannot be mixed with each other to create new colours.
