In the sense of tin, calque of Latin plumbum album (“tin”, literally “white lead”) already used before our era, as well as plumbum candidum (“tin”, literally “white-shining lead”) and Arabic رَصَاص أَبْيَض (raṣāṣ ʔabyaḍ, “tin”, literally “white lead”), distinguished from plumbum nigrum (“lead”, literally “black lead”) / رَصَاص أَسْوَد (raṣāṣ ʔaswad, “lead”, literally “black lead”), as tin and lead were improperly distinguished before modernity.
