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.
