When we talk about aging in artwork, it means how the artwork changes over time. Just like how people get older and things change about them, artworks also change as they get older. Sometimes they can start to look different, or the colors can fade, or it can even get damaged.
Let's imagine that you drew a picture with crayons. At first, it looks bright and colorful, but over time, the crayons will start to fade, and the paper might get yellow. That is what happens when artwork ages.
Artwork can also age differently depending on how they were made or what materials were used. For example, a painting made with oil paints might crack as it gets older, or a piece of sculpture made with clay might break if it's not taken care of properly.
So, just like how we need to take care of ourselves as we grow older, we also need to take care of artwork, so they won't get damaged or look different over time. And sometimes, even if they do change, it can make them more interesting and valuable because people can see the history and story behind them.
