When I was a school student, I applied a drop of (metal) mercury on the (metal) lead found on the joint of a divider instrument of my geometry box. A greyish white material resembling holy ash kept on coming out from it like in a magic show; even when I wiped it off it continued its coming out! This is the Amalgam that is formed by such dissolving of Lead element (Pb) in Mercury element (Hg).
