Ka whakawhanakehia te waro whakahoaho i runga i te oal na roto i te raupapa o nga tikanga penei i te whakangao, te whakamatao, te whakahohe, me te horoi. Ko tona ahua he waro whakakorikori porotakaroa pango, waro whakakorikori matūriki waro amorphous, e mohiotia ana ko te waro kuru. Ko te waro whakakorikori porotakaro, e mohiotia ana ko te waro poupou, he mea hanga mai i te paura o nga rawa mata me nga here, ka konatunatua, ka kohia, katahi ka warohia, ka whakahohehia me etahi atu tukanga. Ka taea hoki te whakakore ma te whakamahi i te waro whakahohe paura me te here. Kua whakawhanakehia e ia te hanganga pore, te pai o te mahi adsorption, te kaha miihini teitei, te ngawari ki te whakahou, me te utu iti; Ka whakamahia mo te purenga o nga hau paitini, te maimoatanga o te hau para, te maimoatanga o te wai ahumahi me te whare, te whakaora whakarewa, me etahi atu waahanga.
