This is a nice set and sizes are convenient, but one of my pans (24 cm) already hangs! I have this set for only a week, I read the instructions for the first wash ... The stove has not tempered, is not mounted too high a temperature, I have burned nothing left, have only cleaned with warm / cold water after complete cooling, did not use abrasive sponges or any metal object in the pan. So I do not understand ... for simple fried eggs while hanging at the bottom of the pan .... defect? misuse (but which)?
