Saucers are a large and confusing category. They are sometimes called "sauce dishes" or "bowls", they get mixed up in auction sales and do not get matched with their original cups and, they are fragile and they or their cups have been replaced over the years. Practically all are of late manufacture, some are marked "China", many are not. Some are flat, some are more bowl shaped, some have little insets for cups, most do not.
