Your cast iron seasoning may be flaking off due to a few reasons, such as not applying enough oil during seasoning, using high heat, or not properly cleaning and maintaining the pan. Re-seasoning the cast iron with multiple thin layers of oil can help prevent flaking in the future.
To clean a seasoned cast iron skillet effectively, use hot water and a stiff brush to scrub off any food residue. Avoid using soap, as it can strip the skillet's seasoning. Dry the skillet thoroughly and apply a thin layer of oil to keep it seasoned.
To season cast iron on the stove, start by heating the pan on low heat. Rub a thin layer of oil all over the pan, including the handle. Let it heat for about an hour, then turn off the heat and let it cool. Repeat this process a few times to build up a good seasoning.
After the first seasoning, the cast iron will be ready to use and the patina (black natural non stick coating) will continue to build. If you care for the pan properly, you won't have to re-season it. But if you scratch off the patina (in the dishwasher or with a scouring pad), or you notice rust. You will need to re-season it. If it's rusting, you will need to scrape the rust off first.
Some cast iron woks come with a coating to protect them from rust before you buy them. (After you have your wok you ought to keep is seasoned to protect it from rust.) This coating is food-safe and cooks off. If it bothers you try putting a decent amount of oil in the wok (like a cup or more) and cook on high heat moving the oil around to get the sides. You should be able to cook most of the coating off. After the coating is gone you will want to be sure that you are properly seasoning and storing your wok. Check the manufacturers instructions or Wikianswers for information about seasoning cast iron.
To effectively repair a cast iron pan, start by scrubbing off any rust with steel wool or a wire brush. Then, season the pan by coating it with a thin layer of oil and baking it in the oven. Repeat this process a few times to build up a non-stick coating. Regularly maintain the seasoning by cooking with oil and avoiding harsh cleaning methods.
The paint may be flaking off the walls in your house due to moisture, poor adhesion, or old age. Moisture can cause the paint to lose its grip on the wall, leading to flaking. Poor adhesion can occur if the surface was not properly prepared before painting. Additionally, old paint can become brittle and start to flake off over time.
The flaking of rocks due to temperature extremes is called thermal stress weathering. This process occurs when rocks expand and contract due to heating and cooling, leading to the outer layers flaking off.

To safely clean a burning cast iron pan, turn off the heat source and allow the pan to cool down. Once cool, use a non-abrasive sponge or brush to scrub off any burnt food. Avoid using soap, as it can damage the seasoning of the pan. Instead, use hot water and a small amount of coarse salt to scrub the pan clean. Dry the pan thoroughly and apply a thin layer of oil to prevent rusting.
