Aluminum foil can become hot when placed in the oven, as it conducts heat efficiently. The length of time that aluminum foil stays hot in the oven depends on various factors, including the temperature of the oven, the thickness of the foil, and the amount of time it has been exposed to the heat source.
Aluminum foil rapidly absorbs and conducts heat, so it can become hot within a few minutes of being in the oven. The higher the oven temperature, the quicker the foil will heat up. Additionally, thicker foil may retain heat for a longer duration compared to thinner foil.
Once removed from the oven, aluminum foil will cool down gradually. The cooling time can vary depending on the ambient temperature and the thickness of the foil. Thicker foil may take longer to cool down than thinner foil due to its greater heat retention properties.
It's important to exercise caution when handling aluminum foil that has been in the oven, as it may still be hot. Use oven mitts or other heat-resistant gloves to protect your hands and avoid direct contact with the hot foil until it has cooled down to a safe temperature.
