Yep i was into around an hour of it too and i was even using a drill with a pait mixer end on it.Volcano? I too usually get a volcano exactly one hour into my hot process. I time it, watch for it, and stir like hell when it starts.
I am using mostly Olive oil then castor and coconut oil. Its ok then to take it off the heat a little before it starts turning into paste?You might want to reduce the heat somewhat, if you can. If using a crockpot, and you can turn it lower or even off temporarily, that can help. I've had soap totally boil over onto my worktable. What a mess, but it got it really clean. Still, just a slightly lower setting helps a lot. Also what oils are used makes a difference. CO likes to heat up and create volcanoes so it requires closer attention and quick response to prevent those boil-overs.
I always thought i had to mix it until it turned inti paste, the emulsion point is when its pretty thick, a few minutes before it turns to paste?Why are you even cooking it? Get it to emulsion and walk away. It will gel by itself.
What do you mean here when you say dilute it?You do not have to cook it. You just mix it until it no longer separates. Then you put a lid on the pot and come back and check on it in a couple of hours. It should be gelled by then. If it is gelled (vaseline appearance), check for zap. If there is no zap, dilute it. No cooking for hours, no boil overs.
