Four colour swirl soap (that went crumbly :( )
I have no idea why, I am sure I measured the ingredients well, my scale is good and moreover, I used a recipe I did once and turned out well.
I suppose, there is maybe a problem with false trace, but wouldn’t than there be parts of lye in my soap? Or at least a watery layer?
Moreover, I used 10% superfat, so if there was a slight excess of lye, it would not be that bad!
|EO Palmarosa||9 ml|
|EO Mandarine||15 ml|
NaOH at 49°C
Oils at 29°C
Mold: old shoe box lined with baking paper
I gave the mixture couple stirs with blender. I didn’t want a thick trace and I knew it will take me some time to make the swirl. During whole process, there was no separation of oils and lye…
I mixed 3 parts of soap with colors and let the fourth uncolored.
Then I started to pour the soap, altering colors in the following manner, until I had no more soap left. I inspired myself by this video: http://www.youtube.com/watch?v=XDYXoDlSoco&feature=autoplay&list=PLC150217FBF4AA1B5&index=14&playnext=2
I did the diagonal swirl…
… followed by round swirl
I left soap three days in covered box, without touching it, and without insulating it.
Today I opened the box and it looked like this:
But when I cut it, i found that the soap is soft and crumbly, but not dry. It is rather like a pasta of a cake, I took some scrapes and put in a small plastic pot, this is how it looks like after passing with a finger:
The phenophtalein test went like this…
Update 25. September 2011 – the soap after a month or so was not that crumbly anymore and I was able to cut it. However, a large portion of soap, mainly where it was not insulated – top and sides – was still crumbly. The middle and bottom parts of soap seem more like a soap. I cut the crumbly (and according to phenophtalein test still caustic) parts of it and got pretty nice bars of soap, although half of their original sizes.
SO WHAT DID I LEARN?
1) If you have liquid trace, you have to insulate your mold. Otherwise, the saponification will slow down as there is not enough heat being generated by the reaction itself and as a consequence, lye will not react well with oils and will rather react with air to create thick layer of soda ash.
2) To be on safe side, make the trace a little thicker.
