That is the question! Whether tis nobler to insulate such soap and allow it to gel, or to take arms against the heat of saponification and use fans to prevent gelling – that is what I am trying to discover. (Pardon me for writing another post that will only make sense to other soapmakers.)
Do you ever find yourself wondering why you use certain methods when you make soap? I can remember learning early on from other seasoned goat’s milk soapmakers that you should prevent gel – either by putting the raw soap in the refrigerator or even the freezer right after pouring, or by using a fan. I’ve been forced to use a fan since my log molds are too long to fit in a refrigerator or freezer. The reasoning was two-fold: 1. The milk heats up the soap and can cause it to volcano out of the mold, and 2. Ungelled soaps are lighter in color. You can see my tutorial on making Oatmeal, Milk and Honey soap here.
Suddenly, after years and years of making my Creamy Castile soap, I find myself questioning this reasoning because sometimes it comes out crumbly around the bottom edge. It only happens with the castile soap – not with any of my other goat’s milk soaps.
I thought I found the solution to the problem after the last batch when I decided to wait on pouring the soap until it finally reached a medium trace. This took a LONG time! I had to blend, wait 15-30 minutes, blend again, wait 15-30 minutes. I don’t even remember how long it finally took! I used to pour as soon as it reached a light trace, thinking it would heat up and start to gel if I didn’t.
Last week I tried using the same method again – waiting until medium trace – and ended up with 50 bars of partially gelled and crumbly soap. It’s either going to have to be re-batched, or sent to Clean the World. I have a feeling it will be the latter.
This made me think – could I possibly make Creamy Castile soap and actually allow it to gel? It went against everything I thought I knew!! Lo and behold – it worked. The soap I made yesterday turned out smooth throughout. There was no volcano, and the color is just slightly darker. Amazing!
So now I’m wondering. Those of you who make goat’s milk soap: do you let your soaps gel, or not? Any other words of wisdom you care to share are much appreciated!
