External heat-resistant coating
You do not want to end up using cookware that is blackened and covered in carbon deposits. Not only are these marks unsightly but they are also unhealthy and can lead to you cooking inferior dishes. All in all, they are best avoided and this is done through the specially designed outer coating that protects the surface from carbon deposits, facilitates maintenance and maintains its original appearance for a long time. So you are saved from spending too long at the sink and can rely on gleaming cookware time in time out.
