Nowadays, ceramic coatings are very popular. I have bought ceramic-coated non-stick pans before, but based on my personal experience, they are not that great. This type of ceramic coating is essentially a gel. It only mimics the texture of ceramic and is not real ceramic by nature. Its hardness is comparable to that of enamel, the enamel coating found on many enameled cast iron cookware. It features high hardness and good wear resistance, yet its non-stick performance is average. It works well during the first one or two months of use, but you will soon notice its non-stick effect fading. For this reason, I personally prefer non-stick pans with conventional non-stick coatings. ``` Having talked about ceramic spray coatings, let’s move on to other points to note about non-stick pans. Apart from the inner coating, the pan body itself also matters a lot. Non-stick coated pans are highly sensitive to temperature. Therefore, the pan material should distribute heat evenly to avoid localized overheating on the pan base during heating, which helps further extend its service life. The body of a non-stick pan should not be too thin — at the very least, the base should have adequate thickness. Proper thickness ensures uniform heat distribution.
``` Before using a non-stick pan, preheat it over low to medium heat for a short time. Then crack an egg into it without adding any oil. If the egg slides freely around the pan without sticking, the pan delivers good non-stick performance. This is what a qualified non-stick pan should be capable of. Generally speaking, almost all new non-stick pans perform like this right out of the box, but how long this performance lasts varies. One last reminder: no matter which type of non-stick pan you pick, be mentally prepared that non-stick pans are consumables. No matter how carefully you use them, the non-stick coating will gradually wear out and lose its properties over time. The performance of common non-stick pans tends to drop after around half a year; newer coating technologies may hold up for roughly two to three years. All non-stick coatings have a limited service life. Keep this in mind and choose according to your own needs when shopping. I hope these basics help you find a non-stick pan you like. ```
