Why would you expect the materials used to make potholders to be poor conductors of heat?

Potholders are designed to protect hands from heat when handling hot cookware, so they are made from materials that are poor conductors of heat, such as cotton, silicone, or certain synthetic fabrics. These materials reduce the transfer of heat, preventing burns and allowing safe handling of hot items. Additionally, the insulating properties of these materials create a barrier that slows down heat conduction, enhancing their effectiveness in thermal protection.
