The Society's aim is to increase the knowledge and promote the appreciation of base metal objects of all kinds and historical periods. The term “base metal” encompasses a whole variety of non-precious metals, including copper, brass, iron, bronze, steel, nickel, zinc and lead, which have played a vital part in the development of human society since the earliest times.  Unlike precious metals, these humbler materials were closely involved at every level of society and in every aspect of daily life.  Surviving artefacts from different historical periods, ranging from distant antiquity to times still within living memory, are a source of informative, fascinating and often surprising insights into the everyday lives of our forebears.
