I'd be grateful for some help/advice. I regularly use enamelled wires (or rather dyed polyurethane wires) in my sculptures, in addition to copper and steel. Last year I created several large steel and wire insect sculptures for permanent siting at a large Garden Centre in UK. I used various copper and enamelled wires (many from your company) for the bulk of the structures. Colours varied on each piece, and most of the pieces have retained their colours. However, on one piece, in which I used predominantly blue enamelled wires, with a few greens, the blues have very noticeably faded to pale greeny/yellows now. This started happening just weeks after it was installed.
As I am now launching into another piece requiring similar colours, I want to ensure this fading does not re-occur. Can anyone advise me on my options? Spray the final work with a lacquer/varnish? Which one? You may also be able to explain why the blue colours, in particular, fade in sunlight?
I have returned to working in metal - particularly steel, copper and various wires. There are health issues in welding and soldering, so I try to work outdoors as much as I can in good weather... Just hope I can continue to a ripe old age!
