This is a video with which Leila Arzani uses a small vessel, I think a mug, and pipettes various color droplets to create a form of rainbow marbling. She uses a stick to guide the flow of pattern within the marbling which she is trying to achieve so that when she has the result she is after she can then pick up an artificial nail and quite literally dip it directly in to directly replicate the design. A very interesting video which looks like good fun to do.
Artist Itir Orcun gets her oil paints and her canvas to offer a clear and concise video tutorial on exactly how to best achieve a realistic marbling technique. The result is an explosion of reds and greens in a formation of various sizes of circles. Once she is happy with the way her oil paints have formed as a marbling she then works into it direct with a paint brush to gain extra detailing. A very nice video with a technique where no result can be duplicated. Get your canvas and have fun.
