Silver-anodising is a process that permanently seals in the aluminium and produces a product that is an excellent heat conductor with an easy-release surface. Practically, this makes it rust-free, easy-to-use and results in shorter cooking times. In particular, pastry tends to be crisper due to the heat retention of the product. If anything does stick to an item, a quick soaking will sort it out. Not to be used in the dishwasher as the surface will discolour.
Properly cared-for, silver anodised bakeware will last a lifetime.
