Ka puta i roto i nga uaua o te mata mata i Hexham i Northumberland, Alston i Cumbria, Anglezarke, tata ki Chorley i Lancashire me etahi atu waahi. Ka huri tere te Witherite ki te barium sulfate na te mahi a te wai kei roto te konupūmā pākawa ngāwha i roto i te wairewa, ā, he maha ngā wā ka whakakikoruatia ngā tioata ki te pūkawa. Koia te puna nui o nga tote barium, he nui te kena ki Northumberland. Kei te whakamahia mo te whakarite i te paihana kiore, i roto i te hanga karaihe me te porcelain, i mua mo te para i te huka.
