Concetti Chiave
- Aluminium is a good heat conductor, resistant to rust, and commonly used for utensils like kettles and frying pans. It requires washing with warm soapy water, mild abrasives if needed, and drying with a soft cloth.
- Iron is strong, durable, and a good heat conductor but prone to rust without coatings. It is used for cooking pots and kettles, needing thorough drying and oiling after cleaning to prevent rust.
- Stainless steel, though a poor heat conductor, is strong, durable, and rust-resistant, used for tea sets and saucepans. It should be washed with warm soapy water and dried with a non-fluffy cloth.
- Tin, known for its non-tarnishing property, is often used as a coating on iron to prevent rust and for making cake and baking tins. It requires careful cleaning with hot soapy water and avoidance of abrasives.
