Here's why:

* Metals: Most pans are made of metals like aluminum, stainless steel, or cast iron. These materials are good conductors of heat. This means they allow heat to flow through them easily, which is essential for cooking.

* Insulators: Insulators resist the flow of heat. While some pans might have insulating handles, the main body of the pan is designed to conduct heat efficiently.

In summary: While some parts of a pan might have insulating properties, the main body of a pan is a conductor to facilitate heat transfer during cooking.
