I used a small 6" x 4" canvas block for this piece. In separate pots I mixed black, white, iridescent copper and iridescent gold with Liquitex, PVA glue and a few drops of coconut milk. I poured a little from each pot into a separate pot and flipped this on to the canvas. Before I lifted this off I poured more white around it, then lifted the pot off and moved the canvas around to mingle the paints and create different shapes. It reminded me of a corner of the beach where I live....still having fun....
