What is a baking tray made of?

Baking trays can be made from a variety of materials, but the most common are:

Metals:

* Aluminum: Lightweight, affordable, and heats evenly. However, it can warp over time and may react with acidic foods.

* Stainless Steel: Durable, rust-resistant, and doesn't react with food. It can be more expensive than aluminum and doesn't conduct heat as well.

* Carbon Steel: Similar to stainless steel, but with a thin layer of carbon added for better heat conductivity. It requires seasoning to prevent rusting.

* Copper: Excellent heat conductor, but also expensive and requires special care.

Non-Metals:

* Glass: Clear glass baking trays allow you to see the food while it's baking. They are heat-resistant, but can be fragile and take longer to heat up.

* Ceramic: Non-stick and heat-resistant, but can be more expensive than other options.

The best type of baking tray for you will depend on your specific needs and budget. Consider what you will be baking, how often you will use the tray, and how much you are willing to spend.
