Faasino i le vaega o loo i lalo ma tali le fesili mulimuli ane i le gagana lava lea e tasi e pei o le vaega:  Auala e ui atu ai: E ui lava e lē o aafia nisi o vailaau e faamamago ai le paʻu, ae e iai isi vailaau e matuā malosi lava ma e manaʻomia ai ni auala faapitoa e taulimaina ai. O le vailaau e masani ona faaaogā e faamago ai mea, o le silica, o se vailaau e lē oona, e lē mafai ona liusuavai i le vai, ma e papaʻe. E faitau sefulu afe tone e gaosia i tausaga taʻitasi mo lenei fuafuaga. O isi vailaʻau masani e faʻamago ai mea e aofia ai le koale faʻagaoioia, kalisiu sulfate, kalisiu chloride, ma faʻamaʻi faʻamaʻi (masani lava, zeolites).  Fesili: O ā nisi o vailaau e masani ona faamamago ai le paʻu?
