Why Do Paintings Last for Centuries — And Why Do Some Fall Apart?

Imagine you're painting a picture with crayons. If your paper is wet, the colors might smudge or run away from each other, just like how paint can fade or fall apart over time. Some paintings are made on strong canvases and use thick paints that hold up well, while others might be on weaker surfaces or use thin, watery paint that breaks down easily.
