This barnacle cluster with a pop of color is about 2.5 inches in size and is a wonder to view. I created murrine to represent barnacles found in the ocean. I placed the murrine on green and blue colored glass as a base and used clear glass to create a underwater magical moment. Finally using a graphite mold the glass is shaped into a perfect sphere.
You can watch a similar marble being made:
