Aluminum has a high melting point of 660.3°C (1220.5°F), which is much higher than the typical cooking temperatures used on a stovetop. This means that the aluminum pot can withstand the heat without burning or melting. Additionally, aluminum has a strong oxide layer on its surface that forms naturally when exposed to air, which further protects it from burning or reacting with the food being cooked. This oxide layer also prevents the aluminum from leaching into the food, making it a safe and durable material for cooking pots. **
