This style of marbling was different than the usual spreading of paint around the vat. After spreading a little bit of watered down acrylic, I sprinkled this treated water over it -- I'm sorry to say I can't remember what was in it -- and the paint separated into tiny strips, stripes, curves, spaces and all sorts of other craziness.
