The product is made of silicone and fiberglass, providing a sturdy and high-quality construction. Food-safe silicone embedded with fiberglass fabric ensures durability and optimal heat distribution, delivering even heating across the entire surface to prevent burnt or undercooked areas. There is no need to re-grease baking trays or pans with spray, oil, parchment paper, or aluminum foil. These reusable cooking mats eliminate the need for greasy oils, sprays, and the additional cost of disposable liners. To protect the oven from food spills and splatters, place the mat beneath other cooking items. This helps prevent messes from burning onto the oven bottom, reducing cleanup efforts and making disposable aluminum foil unnecessary. The mat is easy to clean and reusable. Without the need for greasing or sticking, there is no reliance on baking paper or greasy pans. After use, simply wipe with a sponge and detergent, then air dry. Burnt-on sugar and fat can be easily removed, and the mat is also dishwasher safe. Used globally in commercial catering, bakery, and pastry operations, these food-grade silicone mats are known for their longevity. Ideal for baking cookies, brownies, cakes, french fries, biscuits, bread, rolls, pizza, and more, they are perfect for professional bakers, home baking enthusiasts, and beginners alike.
