I've eliminated the zinc with no change. I was trying to remove some of the off-white, yellow to beige opals but they still develop. The tin seems to push toward the purples, greens and blues. Wish it wasn't so pricey. I'll also try less silver. The reds in these photo are what I'd like to achieve. I sure didn't see anything start to pop out with mercury, but I'm far from exhausting the possibilities with it.
