Many of you have watched me make cold process soap on YouTube, because that is what I do! But sometimes, it’s necessary to do Hot Process. The reason I make my Lilac n Lilies soap using the hot process method is because in cold process the scent dissipates, and isn’t the same as in hot process. To me, you can’t do the same things with hot process as cold process, but maybe that’s because cold process is my method of choice. Hot Process soaps have a rustic look, in my opinion, which is fine. I didn’t video this process as it takes me quite a bit of time, but I did document it, and I will show you my process below.

Here is a picture of my set up. Two stock pots, the bottom one with about 2 inches of water in it. A double boiler method. The top pot has my melted oils and butter in it.

The beginning stages of hot process are the same as cold process, except you do not have to wait for your oils and lye to cool down, because you are going to slowly cook them. The next photo shows the soap as it has come to a thick trace.

This next photo is about 5 minutes later, showing the beginning stages of the slow cook. At this stage it kind of resembles a nice pudding consistency.

The next photo is about 10 minutes later, and you can see the soap is starting to become translucent. The soap has to be stirred frequently so it cooks evenly. You have to be careful here because both the pot and the soap are hot!

This next photo is about another 10 minutes later, and the soap is much more translucent.

This soap has been cooking for about 25 minutes at this point. I just keep checking on it, and giving it a stir every couple of minutes.  The next photo is about another 10 minutes, and the soap is fully translucent.  This is what you want.

I give it a good stick blend at this point, just to make sure there are no little bits left.  Then I separate out some of the soap batter for the top.  The main soap will be a lilac colour which I have coloured with a light purple mica.I have added my Lilac fragrance to my colorant, and added them together.

Next after mixing, mixing and mixing, I pour into the mold, and give it a couple of good bangs to get any air bubbles out.  The last step is to add the white soap to the top.


Below is a video showing the cutting of this soap.  Some people don’t cure their soap when they hot process it, but I do.  I still cure it for 4 weeks, to make a nice long lasting bar of soap.  Thanks for reading and watching! ~ Darlene
