I like that one too, Howie! The layering idea makes for more interesting use of the bar as well, don't you think? Oh, your patience in pouring so many dots so precisely is something I admire.
I am very heavy handed with micas and I think I used 8 or 9 colors across a range, which makes it pretty colorful. Not everyone likes that much going on in a bar, but that's a style thing. I pour thin lines of each color twice (so 16-18 lines) across the slab, then zig zag across the lines from side to side, but not super close, then zig zag across those lines from top to bottom. (You can pour the first lines of soap across the short length of the mold and then zig zag from top to bottom and then side to side depending on which way you want your thin lines to run.) You get very very fine lines of color that way. From that Taiwan look, you can finish with another swirl to get your final pattern. The trick is doing it all with your soap still pretty fluid.
