Secondly, you can choose from the leather material. When choosing, you can carefully observe whether the surface of the non-stick pan is smooth, whether the colour is even and whether there are any obvious defects on the surface, such as dirt, cracks and bubbles. At the same time, when choosing a non-stick pan with a larger diameter (30cm or more), pay attention to whether the handle is firmly attached to the pan body.
Third, pay attention to checking the non-stick and easy-to-clean properties. To determine whether a non-stick pan is up to scratch, a simple non-stick test can be carried out: first test the surface of the non-stick pan with a soft cloth dipped in vegetable oil, then wash it with warm water and detergent, then rinse with water and wipe dry. While the non-stick pan is burning at a temperature of 1500°C to 1700°C, place fresh eggs in the pan without oil and leave to set and then flip. The eggs can fall freely and are a certified product.
