Macdanta waxaa loogu magac daray William Withering, kaas oo 1784 u aqoonsaday inay kimikal ahaan ka duwan tahay baryte.

Waa isha ugu weyn ee milixda barium waxaana laga soo saaraa xaddi badan Northumberland. Waxaa loo isticmaalaa diyaarinta sunta jiirka, soo saarista dhalada iyo foornada, iyo markii hore sifaynta sonkorta.Waxa kale oo loo isticmaalaa xakamaynta saamiga chromate ilaa sulfate ee qubayska chromium electroplating.
