Marble paintings are created by using water and oil paints. Since water and oil don't mix, only the oil attaches itself to the paper, creating fun designs. No two paintings can ever be the same, even if you use the same colours. Kids love creating marble paintings because it is a messy activity! Here is how you can create a marble painting with your child.
Lay out some newspaper. This craft is messy, and you want to protect the surface of your work area. You may also want to wear a smock or apron to protect your clothes.
Get out your rectangular pan (the pan should be a little bigger than a regular-sized piece of paper) and fill it most of the way with water.
In a bowl, mix your oil paint and some white spirit. You want the paint to be runny. Start out using only two colours of paint until you get the hang of it. Then, the next time, you can add three or four colours. Don't do any more than that, though, or the paint will begin to mix together.
Take your paintbrush and drop dabs of paint into the rectangular pan. Once you get enough dabs in there, use your stick to swirl the colours around. This is what gives the craft a marbleised look.
Now gently lay your paper on the surface of the rectangular pan. Check for any air bubbles that could be trapped under the paper and gently smooth them out. Leave for about 10 seconds.
After 10 seconds, remove your paper from the rectangular pan. Place your paper on a dry patch of the newspaper that's across your workspace. Let sit until completely dry.
Frame your marble painting and display it in your bedroom. Or give it away as a present.
