I was investigating what happens to acrylic paint when you add marble dust. I have used it cold wax and oil media, as well as printmaking inks, to stiffen the consistency of the material. So what happens if you work it into acrylic paint?
Looks like we've found a way to make transparent acrylics opaque without adding white, which changes their value.
