Abstract:		 Loss of arsenic from the arsenical copper typical of the British EBA was found experimentally to occur only under oxidising conditions. No loss of any practical consequence was observed under non-oxidising conditions at temperatures of up to 1150 C. The deliberate control of the arsenic content of EBA metal by melting and working in oxidising conditions seems highly probable for halberd rivets. Finally, arsenic losses under such oxidising conditions and surface arsenic gains by inverse segregation must reduce the reliability of that element as a provenance parameter. It seems likely that other metallic impurities could also be subjected to variable segregation during casting of arsenical copper, and caution in use of rigid analytical levels as an indication of provenance seems desirable.
