Silverwoods bakeware is perfect for all baking needs. The silver anodised material draws in heat & distributes it evenly through the pan leaving no scorched hot-spots or soggy bottoms. When it comes to freezing, the same high conductivity properties mean that you can freeze, quickly & efficiently. When you need to defrost, warmth will be quickly absorbed via the pan & into your food. The anodised surface will not blister or peel & will not rust. Not dishwasher safe.
