Fatty beige layer on colored soap

[grumpy_owl]

BB's Queen's Purple Mica. It's fine inside, except for the ends, but what in this green and holy land is that lardy schmutz on top?!?! Any help troubleshooting this dog would be appreciated.
Oh, p.s. It's not ash. It doesn't wash off. I shall have to plane it off.

It looks like a combo of ash and partial gel to me.

I've had ash that doesn't wash off easily before and had to be planed off. The top looks like ash. However, the bar with the top beige layer looks like it might be due to partial gel. I wonder if you popped it in a warmed oven for a bit if it would correct that even though it's already cut.

Thanks, galaxy! It kind of smeared when I tried to wash it off (I use a net scrubbie for ash and it scrubs off, doesn't smear like a fatty substance) and that whitish layer you see on the bottom right soap is still there, from where it was trapped in the silicone. Also, the white-beige, old-fat color was what the whole soap turned when I poured it. I zap-tested and it feels okay, but I'm still worried. If none of y'all ever saw such things before, I'll just forget about it. But I very much hope I have not invented a new soap fail.
