Green Sawblade Swirl CP Soap Tutorial for Soap the Rainbow.  I was invited to participate in the Soap the Rainbow challenge by Bramble Berry, click HERE for details.  In addition, I could produce any soap design in one main color and was given the color green.  Who couldn’t resist?  I ended up creating two soaps, one CP and one MP.

This tutorial will walk you step by step in creating a sawblade swirl in CP soap.  Furthermore, all of the ingredients can be found on the Bramble Berry website, or you can click on the individual ingredients or equipment.

Green Sawblade Swirl CP Soap Tutorial – Soap the Rainbow

Difficulty: Advanced
Time: 1 hour
Yields: 5 pounds of soap
Recipe type: Cold Process Soap
Ingredients & Equipment:
By weight unless otherwise stated
54 oz Swirl Recipe Quick Mix
20 oz Distilled water, by volume
7.4 oz Sodium hydroxide
3 oz Wasabi fragrance oil
1 tsp Green oxide
1 tsp Kermit green mica
and 1 tsp Evergreen mica
Standard soapmaking equipment plus the following:
5 lb Slab mold
3 Easy pour mixing and measuring containers
Wilton fondant and gum paste tool



Follow proper safety guidelines for making cold process soap including goggles, gloves and long sleeves. Kids, pets, and distractions should be away from work area.


Begin by prepping your ingredients.  Measure the fragrance oil and set aside.  Pigments have a habit of remaining clumpy, so add about 1 tbsp of your quick mix oils to one container and blend with the green pigment using a mini-mixer working out any clumps.  Do the same with the kermit mica in another container and evergreen mica in a third container.  Line the slab mold if necessary.  Set your ingredients aside.

 Step 1:

Mix the lye and water solution and set aside. Melt the oils.  Allow the oils to cool to 100-110 degrees F.  Allow the lye to cool a few degrees cooler than the oils.  Add the lye solution to the oils and mix with a stick blender. At a thin trace (like cream) add the fragrance oil and blend.

 Step 2:

Pour equal amounts of soap into the 3 pour containers.  It will not all fit, so only fill containers about 2/3 or 3/4 full or 20-25 fl oz.  Leave the remaining soap in the bowl.  Starting with the lightest color (Kermit green), quickly stick blend the soap until it is just blended.  Repeat with the Evergreen container and finally the oxide container.  Most people like to swirl soap at a very thin trace, but this does not mean you can’t swirl at a moderate or even thick trace.  In fact, your trace will dictate the final design.  My soap thickened as I blended, and I used that to my advantage creating a raised, textured surface on my final soap.  Just don’t panic.

Step 3:

Begin pouring most of each green colored soap into the mold randomly.  Leaving about 1 cup of each in the containers.

Using the swirling tool, you can make a quick snaking motion working across in one direction of the mold and then again perpendicularly, but this is completely optional.  It will create a hidden swirl that will appear as the soap is used.

 Step 4:

Next, place the remaining uncolored soap from the bowl on top of the swirl and spread smooth.

Step 5:

Pour a couple of large circles of Kermit mica onto the soap surface, anywhere.  If your soap is thin, it will be easier to pour, but may sink below the top layer of soap, so pour slowly holding the pour container close to the surface.  If your soap is thicker, as shown, plop the soap on the surface and spread it outward.  Repeat this with the other colors, saving a little of each for more circles.

Step 6:

Now pour, or plop as the case may be, smaller circles of alternating color on the previous circles.  It will look something like this picture.  If your soap is thick, carefully give the mold a few whacks on the counter to help the top layers of soap settle.

Step 7:

Using the swirling tool, place the tip about 1/4 inch into the edge of any green circle.  I started with one of the larger outer rings in a corner, but there is no order you have to work in.  Drag the tool from the green to the white in a looping design around the circle.

Think of drawing fat cursive style l’s so that it crosses through only the green and the white.


Because the design is to flow in loops, do not lift the tool unless you have finished the circle or you’re hitting the mold.  Repeat this process for all of the circles – big or small.  The trick to the design is to only pull the tool through two colors.  In addition, pulling it through more than two colors creates a completely different type of swirl.

Step 8:

Once each circle looks like a sawblade, place your dividers into the mold, if available.  Allow to set for 24 hours.  Finally, release the soap from the mold and allow to cure for 4-6 weeks.

When the soap is unmolded and cut into bars, you’ll see that only some of the circle edges show up on each bar.   Moreover, you can actually create many different looks with this technique.  Try changing your colors, use different sized circles, or thin or thicken your trace.
