In a large bowl, combine baking soda, citric acid, and kaolin clay. Mix ingredients thoroughly. Be sure to break down any clumps. I find it easiest to sift the ingredients.
After the dry ingredients are thoroughly mixed, add in sweet almond oil and fragrance oil and mix with whisk or by hand.
In the same bowl, slowly pour in witch hazel and mix with whisk while pouring. The mixture will begin to slowly bubble/activate but mixing while pouring will minimize this.
Add mica to the mixture and mix until it can be firmly squeezed and hold together.
Pack the mixture into the mold. If your shower steamer mixture starts to dry out, spray witch hazel and mix.
Let the shower steamer sit in mold for 24-48 hours then remove.
In order to create paint for the shower steamer, mix a few drops of 91% isopropyl alcohol with a pinch of mica and stir until smooth and paint on with a thin paint brush. Please see the link section down below for all micas used.
Sweet almond oil can be substituted for grapeseed oil, sunflower oil, safflower oil, or your favorite liquid carrier oil.
Shower steamers are best packaged in shrink wrap or stored in an airtight container.
To use a shower steamer, break off a piece and place it out of direct stream of water but where it can occasionally get wet. Can also be placed on a shower shelf.
