Make your infused oils. Heat your olive oil over medium-low heat. Add in your tea bags and set to a simmer. After a few hours, strain your oil using a fine sieve and then again with a coffee filter or cheesecloth.
Repeat the same steps, this time infusing the coconut oil with lavender buds.
Weigh your ingredients for soap making.
Combine all the oils and shea butter over low heat until 115°F. While heating, add your lye to the water in a heatproof container. Stir until completely dissolved. Place in an ice bath until it also reaches 115°F.
In a large mixing bowl, add your lye water to your oils. Use an immersion blender to blend until it reaches a light trace.
Add in your essential oils and benzoin resin. Blend again.
Pour into a soap mold. Sprinkle the purple mica powder on top and use a chopstick to mix through the soap.
Sprinkle butterfly pea flowers and lavender buds on top.
Let soap rest for 48 hours wrapped in a towel.
After 48 hours, cut the soap and let it cure for 6 weeks in a cool, dark location.
