Visiting Tarpon Springs, Florida recently, I noticed the fondness that the Greek folks have for olive oil soap and uses of the sea sponge that are brought up on the docks, indigenous to the Gulf coastal waters in Pinellas County.
Not the best picture but I made a small batch of soap with coconut, palm and rice bran oils; added Australian black clay and fragranced with a blend of black sandalwood and black pepper oils. I added the sea sponge on top to finish. I like the look and it smells divine!
