Slowly and carefully add the lye solution to the oils. Set the Easy Pour Container to the side to use again to hold soap. Don’t worry about cleaning it out. Pulse the stick blender on and off to begin blending the oils and lye together. Continue to pulse the stick blender for 15-20 seconds and use the stick blender to stir the mixture.
Once you start blending, the mixture will begin to look creamy. After about 1 minute of blending and stirring, the oils and lye are combined and the soap will be the texture of thin pudding.
Add the fragrance oil to the soap batter. Use your whisk to combine thoroughly.
Split half of the soap into the Easy Pour Container previously used for lye. To this container, add all of the dispersed green colorant and whisk in. It turns a mossy/army green at first, but don’t worry! It will turn bright green after 24 hours.
You now have a container of uncolored soap and a container of green soap. You want the soap to be slightly thick - it should look like cake batter. If it’s still the consistency of thin pudding, stick blend each container from lightest to darkest color for 5-10 seconds. The thicker texture allows you to get defined layers.
With one of spoons, place 3-4 large dollops of green soap in the mold. Then, place 3-4 dollops of uncolored soap on top of the green soap. Keep plopping green and uncolored soap into the mold in this pattern until it is used up. Every once in awhile, tap the mold on the counter to get rid of air bubbles. Vary the size of dollops to create interest.
When the mold is full, tap it firmly on the counter again to release bubbles. Then, take a spoon and start pulling soap toward the center to create peaks. You can also create swirls or divots with the spoon. There is no right way to do this, so have fun with it!
Once all the soap is in the mold, tap it on the counter to help get rid of bubbles. If you'd like the soap to go through gel phase, cover and insulate the soap for 24 hours.
Allow the soap to stay in the mold for 3-4 days. To remove, pull the sides of the mold away from the soap to break the airlock. Push from the bottom to remove the soap. Cut into bars, and allow the bars to cure for 4-6 weeks. Enjoy!
