This underwater wonder marble is about 2.5 inches and is a beautiful representation of a barnacle bloom. I start by creating murrine that is similar to the barnacles found in the ocean. I then use glass in colors of blue , green and white to create a underwater vision. I use a graphite mold to shape the marble into a perfect sphere. A video is available to see a representation of how this beauty is made.
