How to choose aluminum pot?

How to choose aluminum pot:
1. Check whether the surface of the pot is smooth.
2. Check whether there are any defects on the surface of the pot.
3. Look at the bottom of the pot. The part where the bottom of the pot touches the fire is commonly known as the butt of the pot. It is necessary to choose a pot with a small buttocks, which can transfer heat quickly and save time to generate fuel;
4. The pot is divided into thickness, thin is better. Some iron pans may be thick on one side and thin on the other, which is caused by the dislocation of the model. This kind of pan with uneven thickness is not good.
5. When purchasing, turn the bottom of the pot upside down, hold the center of the concave surface of the pot with your fingers, and tap with a hard object. The louder the pot sounds and the greater the vibration, the better. This method can also be used to test the pot for cracks. Cracks are generally prone to occur on the sides of the pan, as they are the thinnest.
