Once the cake slices were dried and fired, students learned how to use tempera paint on clay. I showed them how to mix colors (tints, shades and new colors) on and off the clay. If they mixed the colors on the clay, they were able to create gradients. Students did an amazing job with this and some cake slices turned out very realistic and others looked like they stepped out of Willy Wonka's candy land! Everyone was very happy with their work by the end!
