Can aluminum explode or cause fire in the oven when heated?

While aluminum can oxidize and react with oxygen, it does not typically spontaneously combust or cause explosions in the oven. However, if aluminum cookware is subjected to very high temperatures, it can undergo a process called "dry oxidation" where it reacts rapidly with oxygen to form a layer of aluminum oxide on its surface. This reaction releases a significant amount of heat, which can cause the cookware to overheat and potentially release flammable fumes or catch fire if the temperatures are high enough.

To avoid any safety risks, it is essential to follow the manufacturer's instructions for using aluminum cookware in the oven. Generally, aluminum pans are considered oven-safe up to certain temperature limits, and it's important to stay within those limits to prevent any potential hazards. It's also advisable to avoid using damaged or worn-out aluminum cookware in the oven, as they may be more prone to overheating or releasing fumes.
