Lets talk about Bullseye...

[flame n fuse]

Retroglass http://www.retro-glass.co.uk/ in Alloa sell bullseye sheet, frit, stringers, confetti etc, and some rods, worth a visit as they're not too far from Edinburgh (if you've got a car). If you want a particular colour, call them first. They don't do mail order. They're very helpful.

The bullseye web site has a lot of useful information about the different chemistry of the colours, what reacts, how to coax the best colours etc. They have gorgeous greens and blues, and the lustres are interesting.
