Use the scale to measure out your ingredients.
Heat oils and cocoa butter over low heat until they reach 115°F.
Combine your lye and water in a well-ventilated area. Stir continually until fully dissolved. Then cool in an ice bath until it reaches 115°F.
Add your lye water slowly into a large bowl with your oils. Use the immersion blender to blend until it reaches a light trace.
Add in your essential oils and blend again.
Add the turmeric powder to the edge of your bowl. Use a spatula to make small circles around the entire bowl until you have a large orange circle around the rim. Use the spatula and run it through the whole soap a couple of times.
Pour into a 2 lb soap mold and wrap it in a towel. Leave somewhere warm for 2 days.
Cut your soap into equal slices. Let it cure for 6 weeks in a dry, dark location.
