This unique mat is composed of fiberglass and is coated on both sides with non stick silicone, allowing for the dough to be rolled out effortlessly. The World Cuisine silicone ski-resistant counter pastry mat is ideal for kneading, beating and rolling dough or working with sugar and chocolate. This mat can withstand extreme temperature ranges, however it is not designed to be a baking mat and should never be folded or cut in order to fit in a conventional oven.
