STONE SOAP © is a heat and pour 100% natural glycerin soap. I have added sweet almond oil (skin conditioner), grapefruit seed extract (antibacterial, preservative, anti-fungal) and either essential oils or a combination of essential & fragrance oils or just fragrance oil.
In the center of the soap is a flat glass marble. When you are finished with the soap you end up with the piece of glass that you can keep and stack on the side of your tub...toss it in a plant...make a wish...skip it on a pond...or recycle it!
