I first made this soap in 2012 and it’s been a favorite of my customers (and myself) ever sense. It’s a pretty easy soap design (just takes a bit more time than a typical batch of soap to make).
For the sake of this tutorial we’ll do a 2.5 lb batch of soap. You can scale this up to a 5lb or 10lb if you want.
Oil(s) Selected – 2.5lb Batch
Castor Oil – 1.40 oz
Avocado Oil – 1.40 oz
Coconut Oil (76 Degrees) – 5.60 oz
Olive Oil – 9.80 oz
Palm Oil – 5.60 oz
Cocoa Butter – 4.20 oz
4% Lye Amount – 3.90 oz
Water – 8.25 oz
Yields – 41 oz
- Heart Embed Mold
- Loaf Mold
- Colors (3)
- Fragrance/Essential Oil
Since this design is using embeds it will be a two day process to make this batch of soap. We first need to make the embeds, let them harden over the next 24 hrs, and then make a second batch of soap.
I get my heart molds from Bramble Berry, but any heart mold you have will work. Each mold holds approximately 4.5oz of soap.
- 2.5lb Batch – you’ll need 1 heart mold
- 5lb Batch – you’ll need 2 heart molds
- 10lb Batch – you’ll need 3 heart molds
For such a small amount of soap (4.5oz) I recommend just taking it from another batch of soap that you’re making. Or, as I do, I plan out all the different embeds I want to use for a series of soaps and make a batch and separate it up to make the required embeds. That allows me to get my embeds done all in one day.
I typically use white for my hearts and then two contrasting colors for the layers. Because the heart is such a small amount of the overall soap in the finish bar I don’t usually add a fragrance to my heart. This ensures that I also get a pure white heart because the fragrance can’t mess with the color.
Let your heart harden for 24 hours and then unmold.
Now we’ll begin the actual batch of soap.
Make your batch of soap. You make use the recipe above or your own recipe. Once your oils are melted and cooled and your lye solution is ready mix them together to reach a light trace.
Separate out 12oz of soap and set aside. This is going to be the top part of our soap.
In the remaining mixture in your pot add the color you want to use for the base. Mix well.
Add your fragrance to the base mixture. Once it’s thorough incorporated pour the base into the mold.
Note: I add the fragrance to each portion separately. I need the base to set up—to hold the heart embed—but I need the top to be fluid enough to pour over the base. Some fragrances can speed up trace too. I want to avoid that for my top layer. By waiting to add the fragrance it just ensures I have more time to create my design without problems.
Once the base has harden up enough to hold the embed(s) gently place it in the mold/soap.
Add the color to the top part of your soap. Once thoroughly mixed in add your fragrance. Gently pour over the heart. If you pour over the heart then the soap with spread out over the rest of the mold and you can minimize break throughs of the base layer and hence keep and nice clean line.
Step 7 (Optional)
Add a mice swirl top. Premix 1 teaspoon of mica with 1 tablespoon of carrier oil. Using a dropper/pipette drizzle the mixture over the top of the soap. Then using a toothpick of skewer makes circle/swirls through the mica lines. (Do not mist top with alcohol. It was cause the swirls to run.)
Note on Colors: I find contrasting colors for the heart and base/top work best, but you can do any sort of combination you desire.
These are some of my finished soap designs I’ve used with the Embedded Heart Technique.
Then you can take this technique and do a number of variations on it!
As you can see, I’ve had a lot of fun with this technique over the years!
