Cut up 4 chunks of the chosen soap base, and put them in a glass measuring cup or microwave safe container.
Place the container in the microwave and heat for approximately 35 seconds.
Add in up to five drops of essential oils for added fragrance if desired and stir thoroughly to combine. I recommend eucalyptus or lavender, if you feel the bar needs to have an additional scent.
Place your soap molds on the counter so they will be ready to use once the soap base chunks have melted.
Remove the container from the microwave, and stir in the dandelion tincture to combine thoroughly.
Stir the dandelion infusion into the hot soap base for at least 15 seconds to ensure the thick oil is thoroughly combined.
Pour the mixture into the awaiting molds - unless you want to add additional visual interest to the bar using one of the steps below. It will take roughly two to three hours for standard size soap bars to cure completely at room temperature - or a half an hour in the refrigerator.
If you want the dandelion soap to have a top of exposed dandelion parts, place the desired amount of dried and powdered pieces in the soap molds now - arranging them how you want them to look before pouring in the hot soap base.
If you are using a clear glycerin soap and want the bar to have the look of a suspended floral soap, fill the base halfway full with the hot soap base and then sprinkle in the wanted parts. Allow this to cure for about 3 hours at room temperature on the counter or for about 30 minutes in the refrigerator. Once the first part of the soap bar has fully cured, fill it up the rest of the way with more melted and hot soap base, and allow it to cure as well.
