Our exclusive commercial-quality bakeware features a unique textured surface that promotes ideal air circulation and a double-duty nonstick Americoat and silicone glaze finish for clean food release. Durable folded construction with heavy-gauge wire is warp-resistant and rust-proof. Due to this bakeware's heat efficiency, we suggest monitoring the oven temperature and cooking time for the first few uses, then making adjustments to recipes as necessary.
