Barium Carbonate
O le minerale e faʻaigoa ia William Withering, o le i le 1784 na ia iloaina e eseʻese mai vailaʻau mai barytes.

O le mafuaʻaga sili lea o masima barium ma e eliina i le tele o aofaʻi i Northumberland. O loʻo faʻaaoga mo le sauniuniga o le isumu oona, i le gaosiaina o tioata ma poselane, ma muamua mo le faʻamamaina o le suka. O loʻo faʻaaogaina foi mo le faʻatonutonuina o le chromate e faʻatumu ai le sulfate i le potu faʻamama eletise.
