First, pour the Epsom salt into a large glass bowl and add the baking soda.
Next, add the corn starch into the mixture.
Then, add the citric acid to the bowl. Using a whisk, blend ingredients until completely combined.
Next, add mica powder and stir again.
After the dry ingredients are combined, set them aside. Then, add the sweet almond oil, water, and essential oil to a small jar. Secure the lid, and shake well.
Very slowly, while whisking, add this liquid mixture to the dry mixture. Continue whisking until it is all combined.
Next, fill each of the flower molds evenly with the mixture.
Finally, let the mixture set in the mold for about 24 hours.
Once your lavender bath bombs have set, you can enjoy them as soon as you like!
