Lynne,
Thanks for sharing all of your recipes here!!!! I love light iris gold I have found I love it best when pulled directly from rod - the big honkin' chunks. I also find that I get a lot of striking in the kiln that takes my nice blues that I achieve while torching back to nice yellows and greens while in the kiln... I try to play with my iris yellow last in my day so they are in the kiln the shortest period...
These are with a base of straw yellow, then a thick random black ring around the bead - melted in. Next about 5 parallel lines of raku, then lines random lines of pure iris gold between the raku lines...Then it's burn baby burn... Although these aren't boro looking if you encased them they would be.
