I thought I signed up before writing that post, but I can't edit it! Sorry for screwing up. I want to provide details here. Thank you so far for assistance!
I used that pan JUST on Electric Cook Top in my house. I never knew overheating can damage non-stick surface! Someone asked how do I heat it? I usually oil the surface with Sunflower or Safflower Oil — because they have high smoke points! I usually just use medium or medium high heat. SOMETIMES I crank up the cooktop to max heat — if the pan holds many ingredients and the food is cooking too slowly — or if I want to stir fry rice, noodles, vegetables, seafood like Asians.
At max or high heat, I NEVER leave the pan empty or dry on high heat!!! On low to medium heat, the pan can be empty or dry when I am offloading ingredients and onloading new ingredients. Like if I finish stir frying ginger and rice at high heat, I turn down cooktop to low heat. Then I pour out vegetables. Now pan is empty. Then I pour in my raw vegetables and crank back up to high heat.
Now I have a question. I paid $129.99 + 13% tax in Ontario Canada = $147 for this pan. Can someone fix this damage? Is it economical to fix? Or smarter to buy a new pan? I contacted Zwilling about a replacement.
