The baking silicone mat is heat-resistant and has a temperature range of -40°F to 446°F. 2. [Care Instructions] For best results, we recommend boiling the mat in water for 10 minutes before first use. If you are sensitive to the initial smell of the product, you can also put it in the oven at 392℉-428℉ (200℃-220℃) for 10 minutes. 3. [Non-stick surface] No need to grease the silicone baking mat when using, even dough is less likely to stick to the oven-safe silicone baking mat. Each baking mat is 0.03 inches thick, double-layered and durable. 4.
