Basins are made of copper; as a general rule they are not tinned. In large kitchens there are some that are tinned and others that are not. If untinned they can also be used not only for beating up egg whites, cooking fruits, and jellies, but also for blanching and cooking green vegetables, such as spinach, green peas, string beans, etc., thereby retaining their natural color, giving them a more appetizing appearance.
