Water marbling is the ancient art form of using paint on the surface of water to create mesmerizing patterns. By putting DecoArt's Water Marbling Magic Medium in a pool of water you can then use our Water Marbling Acrylics to create delicate and unique designs directly on the water's surface. When water marbling, no two designs will be alike, the surprise and unique quality of each design is part of the magic and mystique of this ancient art form.
