Is there any way in which the life of a ceramic-coated nonstick pan can be extended?   

Sure, here are some of our suggestions:

  • Wash just with a dishcloth or sponge using a mild detergent in hot water. Avoid any kind of scour-pads
  • using low or moderate heat for cooking    
  • Dont switch the pan from hot to cold too quickly.
  • Wash them by hand – even if the manufacturer claims it is safe with dishwasher
  • Using spoons made of plastic or wood. Metal utensils will chip or scratch the ceramic surface resulting in the less nonstick coating.

As it is heat resistant up to 450 C, can we cook with a ceramic nonstick coated pan on high heat? 

Most meals should be cooked with no higher than medium to medium-high temperatures as a basic guideline anyway. This not only preserves food nutrition but also prolongs any pans life. However, there are some exceptions, such as stir-fries and searing steaks. But even then, during cooking, theres no need to hit super-high temperatures.
