No, this pan is made of natural aluminum and should be hand-washed. Dishwashers can cause discoloration and oxidation on raw aluminum surfaces, which may affect the pan's appearance and performance over time.

Yes, natural aluminum is reactive. It is best to avoid using highly acidic ingredients like tomatoes, vinegar, or citrus directly on the pan for long periods, as they can cause pitting or discoloration. Using parchment paper or a silicone baking mat is a simple way to prevent direct contact.

The 18-gauge aluminum construction and wire-reinforced rim are specifically engineered to resist warping. While extreme temperature fluctuations can affect any metal, this pan is designed to maintain its shape under standard roasting and baking temperatures.

While the aluminum provides excellent heat distribution, it is not a non-stick surface. We recommend greasing the pan, using a light dusting of flour, or lining it with parchment paper to ensure your baked goods release easily.

Gauge refers to the thickness of the metal; a lower number indicates a thicker, more durable pan. 18-gauge is a professional standard that balances weight and heat conductivity, making it sturdy enough for daily use without being overly heavy to handle.
