Some sources specifically describe it as a type of brass with a composition of three parts copper to one of zinc pickled in a diluted spirit of vitriol and then immersed in aquafortis before burnishing. Prince's metal was supposedly invented by Prince Rupert of the Rhine. ]]></dc:description></metadata>
