How Do Paintings Survive for Hundreds of Years?

Imagine painting with a special kind of glue, like the way you use glitter glue to stick paper on your homework. When artists make paintings, they sometimes use a kind of magic glue that keeps their colors bright and strong for centuries. This glue is called a binding medium, and it makes sure the paint doesn’t fall off or get old too fast. Painting preservation works like this, it helps keep the picture looking new even after many years.
