Abstract: A transparent toilet bar with an embedded decorative concentric pattern comprised of colored transparent soap formulations, and a method for producing the bar. The preferred embodiment of the bar is a transparent semi-circular rainbow pattern of three or more colors embedded in a transparent rectangular bar with a glittering agent. The preferred method of producing the rainbow is to pour a first color into a small circular mold and then to place that circular soap article into a larger mold and pour a second color around the soap article. A third concentric ring is created by repeating the process with a larger third mold. The finished disk is cut in half to create two rainbow soap articles. In the preferred embodiment of the method, all soap compositions are identical except for color or glitter additives.
