Melt your oils together in the double boiler until they reach 115°F.
Meanwhile, combine your water and lye together in a Pyrex cup. Stir until fully dissolved and then cool in an ice bath until 115°F.
Using the immersion blender, combine your lye water and oils until it reaches trace.
Separate your soap batter into 3 bowls. One bowl should hold 2/3, another 1/3, and the third a scoop.
Add the essential oils to 2/3 of the soap batter. Mix with the immersion blender. Pour into the soap mold.
Top off with the 1/3 unscented soap.
Mix your gold mica with the remaining scoop of soap. Pour over the top of the soap mold. Use a chopstick to pull through the soap and create swirls.
Decorate one side of the soap with whole dried calendula flowers.
Let the soap sit somewhere warm for 48 hours.
Cut soap into equal sections. Let sit in a cool, dark place for 6 weeks in order to cure.
