This pretty glass is called Tangerine Ltd Run and is one of 9 ltd run colours released by Creation is Messy in America in January 2013.
Left you can see a half and half bead made with Tangerine and Peace (with a wrap of dilute Goldstone stringer) which has been worked for longer and struck several times. You can see that although I have not managed to bring the whole tangerine side to a single colour it looks altogether deeper and richer in tone than the beads in the image above which were worked much less.
