Instructions
Working in a well-ventilated area and wearing proper safety gear, add the water to a jar or container that can handle high heat.
Carefully and slowly add the lye to the water, then gently stir it until dissolved. Note the liquid will shoot up over 200°, so using a container that can handle the rapid increase in temperature is vital!
Set the lye water aside to cool while you do the next step.
Melt the coconut oil, almond oil, and castor oil in a small saucepan over medium-low heat. You can also use a double boiler. However, I’ve found it works just as well using a saucepan while stirring frequently.
Once the oils are melted, you'll want to let it cool down to about 100°F. The same goes for the lye water - wait for it to cool. You may need to wait a little longer for one or the other to cool, and that’s fine.
Now, using a large mixing bowl with tall sides (to prevent splashing), add the melted oils, then add the lye water, just a little bit at a time, and mix with an immersion blender until it comes to a light trace. About one minute is usually enough.
Add your salt and mica powder, and stir it in.
Pour the soap into your prepared soap molds and allow them to harden for 24 hours or up to 3 days before removing them from the molds.
Lay the bars on their ends about an inch apart, and allow them to cure for five weeks before using.
