Wearing gloves, weigh lye in a zip close bag and set aside. Weigh water in a glass or plastic container and take both water and lye outside. Put on goggles and mask and gloves and pour lye into water and stir until dissolved. It will heat as you stir. Allow to cool to around 80-90 degrees Fahrenheit.
3.1 ounces lye, 8.2 ounces water
When temperatures of oils and lye water are between 80-90 degrees Fahrenheit, add lye water into pot of oils and use a stick blender on and off until soap reaches light trace.
Add essential oils and mix well.
0.35 ounce peppermint essential oil
Remove 1/4 cup's worth or more of soap and add rose clay. Whisk to make sure there are no lumps.
1-2 teaspoons rose clay
