Ahhh update...
So, I've just looked at the soap I moulded yesterday... it was pretty warm in its towel yesterday, but it looks to have partially gelled again, like my previous attempt... It doesn't feel like there's any residual heat in it, but I've not unmoulded it, I'll do it tomorrow, and slice it then. Also, like the previous batch that partially gelled, this soap feels softish (certainly softer than my co/po/poo attempts).
Out of the batches I've made so far, the first two worked ok and gelled fine (POO, CO, PO), but the last two only partially gelled (POO, CO, SB, CO [one batch also had SAO])... perhaps the PO is key? More experimenting is needed!!
I had some fab advice from
@DeeAnna yesterday, but I'd already made the soap, so I'm going to see if it helps with my next batch... #notgivingin!
