I never tried the ones under penland additive formulas. I just picked that up sonewhere and never did anything with it.

I've done a lot of the ones on the sheet that's a picture (extracting the coloring oxide percentages) and gotten good results. If my memory is correct, if you melt them as stated you'll end up with expansion over 100. I used those percentages in the phosphates I melted, omitting the bone ash and just using the colorant percentages. They make VERY nice colors.
