What is so unique about this Mineral Art creation is its uncanny ability to change when hit by light in different places on the art. I used a recycled paper sheet of this unusual pulpy paper. From the first grind I knew that the end results were going to be a show stopper. After being moved by the grind of the minerals I poured a mixed polyurethane cold pour. The Mix when it starts to harden seeped into the paper. Then because the polyurethane expands when curing It re appeared a the surface with this bubble texture. Then as the poly mix cured colors appeared on their own addingg even more of a cool piece.
