Homemade Soap Tutorial

This recipe is for the microwave method of rebatching soap. There are other methods that you can use including melting your rebatch base in a crock pot or double boiler.  Click here to read about these methods.

10 drops blue soap colorant
1 Tablespoon Sweet Almond Oil
2 Tablespoons Water
1 Tablespoon Blue Raspberry FO (or any other suitable Fragrance Oil)
1 pound rebatch soap base
Equipment Needed:
Microwave oven
Microwave safe bowl
Large Spoon


Grate or grind your rebatch soap base (not needed if you purchased our shreds base) and heat soap in the microwave for 30 seconds on high in a microwave safe glass bowl. Stir your soap, and then heat for another 30 seconds in the microwave (remove your spoon before putting it back into the microwave again).
Heat for one minute in the microwave, or until you see the soap foam as shown in this image. Here is what ground soap looks like after cooking for 30 seconds, it’s a bit crumbly still. You just want to heat it a bit before adding your sweet almond oil and water.

Stir your soap, and then heat for another 30 seconds in the microwave (remove your spoon before putting it back into the microwave again)

Heat for one minute in the microwave, or until you see the soap foam as shown in this image.


By now your soap should resemble a thick paste as shown in the image to the left. If it does not, heat for an additional 15 seconds and stir well again. Continue heating and stirring every 15 seconds until your soap base looks like what is shown in the image to the left.

Be careful with it, it will get VERY hot. It will foam as you heat it, continue stirring it so that the foam dissolves.

Drizzle your sweet almond oil over the top, an then toss the soap lightly to distribute the water and oil evenly.

Add your blue soap colorant.


Heat your soap for another 30 seconds so that it will warm again, as the colorant will cool your soap a tiny but.


You should see it foam again, if not, try for 10 seconds until you see it forming foam again.

Now working fast, add your fragrance and stir, stir, stir. Your soap will cool some once you add your fragrance oil, and it cannot be heated in the microwave again once the fragrance is added.

The soap will be creamier once you have added your fragrance. As you can see in the image to the left, the soap is a bit smoother.

Once your fragrance has been added, spoon your soap into a mold (here I am using the bottom of a vegetable oil bottle, it’ll peel right off the soap) then using waxed paper press the soap down firmly while protecting your hands with a pot holder to prevent burns.

Next, pound your mold onto the counter by banging the bottom gently on your counter to get rid of any air holes, then press again with wax paper. The top will never get completely smooth on the top, but you do want it as even as possible with no air holes. It’ll be smooth once you cut it.


Let your soap cool completely before unmolding it. If you wish to speed up the cooling time, you can place it in your freezer for an hour to help it cool faster.

Once your soap has cooled completely, remove it from your mold. Since I used a recycled plastic bottle, I was able to simply cut and peel the plastic off of the soap.

Slice your soap into bars.

Here is my cooled soap, with the top sliced thinly off of it.

Below you can see my finished bars of handmilled soap

1 large 6-ounce bar that is a hefty 1-inch thick

4 smaller bars from the bottom end piece, they weigh about half an ounce each. And the top that I had thinly sliced off was rolled into a soap ball that is just under 2-ounces.

Enjoy your new soap. It makes a lovely gift for that special loved one in your life, it can be added to gift baskets, grated for scrubs and/or sachets, you can sell it or you can keep it a secret and keep every little sliver for your own enjoyment. If your family is like mine, then you may want to hide it so that others do not steal it.

My bars of handmilled soaps always seem to walk off on their own, only for me to see that they prefer to live with my daughter, my cousin…by best friend. I never knew soap could decide where it wants to live, but that is the only explanation I can think of because surely my guests would not sneak them out in their purses or pockets.
