Layer of fat on surface of soap coloured red

[Ladka]

I made a small batch of leaf lard soap with the ingredients
Oil % Grams

Lard, Pig Tallow (Manteca) 78.1 189

Coconut Oil, 92 deg 14.88 36

Castor Oil 7.02 17

Total 100 242

After two hours of stirring and pulse SB-ing at about 50-60 deg Celsius the batter was between thich emulsion/slight trace. I poured in a preweighed mixture of FOs (2% of oils weight) and red colour Soapy Fun Seifenfarbe Rot. Poured into moulds and placed into the oven to gel (at 50-60 deg Celsius) and left it overnight.
After some time small bubbles appeared on the surface of the soap, some of the contents spilt over in the moulds that were filled to the brim.
Now see what I got next morning:

I think the soap is going to be OK when cured and I remove the white fatty stuff.
But I wander what went wrong ?

I think it overheated and volcanoed. Let's wait for the experts to weigh in though.

They most certainly overheated. Too hot too long for an individual mold.

i missed that!

Too hot too long for an individual mold.

It contains 80 % of leaf lard that always takes extremely long to trace.
And yes, the oven must have been too hot, it has poor temp regulation below 100 deg C.

Dawni, I fail to see the humour in it. Can you explain please.

Dawni, I fail to see the humour in it. Can you explain please.

The laugh was for the face I made - - > o_o <-- big, googly eyes. The face was for the two hours of stirring - that part isn't funny, it's more like a wow to your patience.

Sorry for the miscommunication.

Did you leave the oven turned on all night?

Personally, I would rebatch this or toss it out. I wouldn't use it as is, even if the grease cleans off.

 

[DeeAnna]

Are you absolutely certain you used NaOH, sodium hydroxide? These factors are concerning to me -- 2 hours to trace, greasy incompletely-saponified soap, soap overflowing the mold, and the bubbly appearance of the bars.

All those things makes me wonder if you used Na2CO3, sodium carbonate, instead.

 

[Ladka]

Dawni, no offence felt here.
Regarding patience, I have it a lot. If my three children hadn't trained me sufficiently, my nine grandchildren have, especially the two pairs of twins.
DeeAnna, I don't have sodium carbonate. The label says Sodium Hydroxide and also that it is used for soap making. I bought it from the same provider as always.
Obsidian, no, I didn't leave the oven turned on all night, just at the beginning.
So, if I decide to rebatch: shall I just melt it, with some water added if necessary, with all the grease, or should I maybe remove the grease or maybe add anything?
Shunt2011, what is too long for an individual mold?

 

[Obsidian]

If you rebatch, chop it up small, grease and all. Heat it on low, add water only if necessary and only a tablespoon or so at a time.
It won't melt down smooth but once its more or less like mashed potatoes, glop it back in the molds.

 

[shunt2011]

I've never left my individual molds in the oven more than an hour or so. That's heating it to the lowest setting and turning it off when I put the soap in the oven. I also wrap it with a towel just to protect the mold/soap. Otherwise I get bubbles or overheating.

 

[Dawni]

It's new soap, yes? It still might melt into molten soap when you rebatch. It still has enough water for it to not be too gloppy. Or if you think it doesn't, add a tablespoon of water/milk/oil n let it soak then rebatch. You still might get pourable, albeit thick, batter.

Yes, it is new soap. I'll rebatch it but will keep one piece unrebatched just to see how it "develops" during curing.
