Grease Casting Art Technique

Try a different technique to make plaster casts. This grease casting technique is so much fun since you can easily "erase" your design and start over.

What You'll Need:

  • Newspaper
  • Blunt scissors
  • Heavy-duty aluminum foil
  • Ruler
  • Shortening
  • Butter knife
  • Ballpoint pen
  • Plaster of paris
  • Plastic spoon
  • Paper clip (optional)

HOW TO MAKE A GREASE CASTING:Step 1: Cover your work surface with newspaper. Cut a 4 by 6-inch square or 6-inch circle from aluminum foil. Fold up the sides about 1 inch.

Step 2: Use a knife to spread a 1/8-inch-thick, even layer of shortening in the foil shape. Press the ballpoint pen into the grease to draw your design.

Step 3: With an adult's help, mix the plaster of paris according to package directions. Carefully spoon it over the grease. If you'd like to hang your plaster casting, press a paper clip into the top edge.

Step 4: When the plaster is set, pop it out of the foil. Clean the plaster casting with warm, soapy water. Let it dry completely.
