Many iron pots commonly used in families are made of pig iron. Pig iron products are hard and brittle, and iron is a metal that rusts easily. If you don't pay attention to protection in use, it is easy to have problems. Here are some common sense of using and protecting raw woks.

1. It's best to get some sawdust, straw and the like for the newly bought wok, and put it in the wok for ignition and baking, which can play the role of "annealing" and change its hard and brittle characteristics.

Then use emery cloth, ashes or straw to smooth the pot. First, boil a pot of water, wash the pot, heat it on the fire, put some cooking oil on it, and then you can cook or fry it. The pot treated in this way can enhance the fire resistance and rust resistance.

There is another way: first wipe off the rust on the pot with a coarse cloth, then put a few spoonfuls of salt in the pot and fry it. After the salt is browned, wipe the pot with it, clean it, and then boil it in vegetable leaf water, and the pot will be smooth.

When the new pot is used for the first time, the fire should not be too big, so as not to burst suddenly when heated. Start with a small fire as much as possible and gradually increase the firepower. It doesn't matter if you use it several times.

When cooking or cooking, you should put water or oil in the pot first. Don't put the pot on the fire before pouring water, otherwise it will easily burst due to sudden heating and quenching. Don't put the pot on the stove when not in use. If the pot is built with a stove, add water to the pot after it is cooked.

4. Try to avoid contact with wet coal at the bottom of the pot, because the gas evaporated from wet coal is very corrosive. After a long time, the iron pot will rust and peel, and loopholes will gradually appear. If the rice is burnt and sticks to the bottom (that is, sticks to the bottom of the pot), you should first gently shovel off the crust with a spatula, and then wash it with water after the pot is cold.

5. After the iron pot is used up, it should be scrubbed clean, and it is customary to wipe off the water drops with a cloth and put them in a dry place.

Because the bottom of the pot will rust when it is wet, there will be loopholes after a long time.

6. There are two simple ways to repair the wok. One is to put edible oil, cotton and lime powder together and beat them with a hammer to bond the three raw materials. This adhesive is used to stick the cracks and holes in the iron pan and can be used after drying. The second is to slice the pig liver and stick it on the outside of the leak. When it is baked by fire, it will be very strong. Pots supplemented by these two methods can be used to steam dry food, make porridge and cook rice, but not to stir-fry and pancake.
