UGC NT - Copper Glow
Creative Glass Guild are pleased to be the exclusive distributor for Unique Glass Colours in the UK. The NT colour line by Unique Glass Colours come in powder form available in a 1oz pot or a pint, 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 cooler the metallic 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.
The NT line should be mixed with the UGC Medium (available separately - click here to purchase) 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.
Average firing range is 773°C to 843°C (1425F to 1550F) but colours can be fired much hotter. We at UGC have taken the colours up to 983°C (1800F) 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 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.
