Can aluminum coils be used for baking bread?

Aluminum coils are not typically used for baking bread. While aluminum is a good conductor of heat and is used in baking sheets and muffin tins, it's usually in a flat, solid form. Aluminum coils, often used for industrial purposes like heat exchangers, are not designed for direct food contact. For baking bread, it's best to use materials specifically designed for baking, such as silicone mats, parchment paper, or non-stick baking sheets. These materials are safe for food contact and can withstand the high temperatures required for baking bread.
