No, it is not recommended to use aluminum cake tins or any metal containers in a microwave oven, including an IFB microwave. Aluminum is a highly conductive metal, and when microwaves come into contact with it, they can cause sparks, arcing, and potential damage to the oven.
Microwaves work by generating electromagnetic waves that are absorbed by water molecules and other electrically polar molecules in the food, causing them to heat up. Metal reflects these waves and can create a buildup of electrical charge, resulting in sparks and potential fire hazards.
If you need to bake a cake in a microwave oven, it's best to use microwave-safe baking utensils made of materials like glass or microwave-safe plastics. These materials are designed to withstand the heating and cooking process in a microwave oven without causing any harm.
Always refer to the manufacturer's instructions and guidelines for your specific microwave oven to ensure safe and proper usage.
