Why Do Paintings Change Over Time?

Paintings don’t just get old, they actually change because of what’s inside them. Imagine your favorite cookie: if it's made with chocolate, it might melt in the heat. Paints are like that cookie. Oil paintings use oil, and over time, that oil can mix with other parts of the paint, making colors look dull or even change shape. Sometimes, you can see cracks form on old paintings, it’s like how an old candy bar gets brittle.
