Thanks, LP, I have the mysore sandalwood, I am going to try it w/that. I have never gone above 33%, so am a bit nervous, but kind of excited! I made a bunch of testers and had batter left over, so did a pour in the slab, you can't even see the pattern for the ash, it is crazy. Like I said, I've never had ash before, so it is really getting to me, have to plane all of the bars ...
ETA: I have been using a slow tracing mix, 60+ lard, which is v. similar to what I usually use w/log molds (rarely used a slab before this challenge). I am convinced that the ash comes from using a slab mold rather than a log one, b/c of the additional surface area. Plus *something* that I am doing, or in my soaping environment, this is just too weird.
I have tried using wooden slab molds and silicone ones, the ash has happened w/both. It seems to be a bit better if I CPOP, but is still much worse than in a log. Honestly, I am kind of mystified, it is just such a dramatic difference. Is anyone else getting this, or is it just me?
I'm attaching a pic, will update with the planed bars so that you can see the actual colors when it ready to be planed (yes, there *are* actual colors under the ash ....)
