Chop the soap base into small squares, around 1-2” in size.
To determine how many cubes you'll need, count 1 to 2 per mold. I made 10 soaps, so I used about 15-16 chopped pieces. If the molds you are using are larger, it would be about 1/8 pound per bar. This part is the hardest, since every mold is different in size. Overestimate by 1 or 2 pieces to be safe.
Now, place the soap squares into the top portion of your double boiler (or your bowl or measuring cup fitted into a pan of hot water. Stir using a rubber spatula and scraping the sides, and mix until the soap is melted, smooth and free of lumps.
Remove the pan from the heat and allow it to cool slightly. Next, add in your essential oils, one at a time, and mix them in well. The lavender and geranium are especially runny ones, so take your time when adding the drops, so that you don’t over-do it. Make sure they are well blended in the soap. You may notice the soap start to thicken and set up again. If it does, place the double boiler (or bowl or measuring cup) back over the heated water just until it melts again.
Give it a stir, and then whisk in your Matcha tea (a bamboo whisk works best for blending matcha powder). This is the crucial part – matcha green tea tends to clump and stay in one spot, so make sure you are whisking it constantly and using a silicone spatula to break up lumps and scrape all edges of the pan to make sure everything is evenly combined. If you need to break it up any tea clumps, use the back of a spoon and push it against the sides of the bowl to mash it up, then mix it in. If the mixture gets too thick as you blend to get it well dispersed, put the double boiler back over the heat to soften it up.
Once it is mixed well throughout and you have no more tea or soap clumps, you're ready to pour it into your molds. You just need to leave a tiny bit of space at the top to help you pop the soap out later. Allow the soaps cool off fully at room temperature. It usually takes about an hour, but it will also depend on the mold size you choose.
Feel the centers of the molds underneath to see if they are cooled. Once they're cool, you can turn the molds over and carefully pop out the soaps. If they are still warm in the center, wait longer as it can dent or cause the soap to be misshapen.
Once you have the soaps all popped out, remove any loose pieces that may be attached from pouring, and the soaps are all set to use. I like to store them in a glass jar, or just place a few on a cute soap dish. They last longer than you may expect, so if you set out too many, they can accumulate dust.
To use, lather up with warm water and wash your face once per day, set by the sink for hand washing or use in shower or tub as you would regular soap in your daily routine.
