Ka taea te wehewehe i ngā taputapu tātari diatomite ki ngā hua rimurimu maroke, ngā hua kua whakapūkaratia me ngā hua kua whakapūkaratia rere, e ai ki ngā tukanga whakaputa rerekē.

① Ngā hua maroke
I muri i te purenga, te whakamaroketanga i mua i te whakamaroketanga me te whakakorikori, ka whakamaroketia te rauemi mata ki te 600-800 °C, kātahi ka whakakorikori. He tino angiangi te rahi o tēnei momo hua, ā, he pai mō te tātari tika. He maha ngā wā ka whakamahia ngātahi me ētahi atu taputapu tātari. Ko te nuinga o ngā hua maroke he kōwhai mārama, engari he mā miraka me te hina mārama anō hoki.

② Ngā hua kua whakapūkaratia
Ka tukuna te diatomite kua purea, kua maroke, kua kuruhia ki roto i te oumu hurihuri, ka whakawerahia ki te 800-1200 °C, kātahi ka kuruhia, ka whakarōpūtia kia puta ai te hua kua whakawerahia. Ki te whakatauritea ki ngā hua maroke, e toru ngā wā teitei ake te uruhanga o ngā hua kua whakawerahia. He whero mārama te nuinga o ngā hua kua whakawerahia.

③ Ngā hua kua whakapūkarahia
I muri i te purenga, te whakamaroke me te huri, ka tāpirihia te rauemi mata o te diatomite ki te iti o te konutai kāponāte, te konutai pūhaumāota me ētahi atu matū rewa, ā, ka whakawerahia ki te 900 ~ 1200 °C. I muri i te huri me te whakatau i te rahi o te matūriki, ka puta te hua whakawera rere. Ka tino piki ake te urunga o te hua whakawera rere, neke atu i te 20 ngā wā o te hua maroke. He mā te nuinga o ngā hua whakawera rere, ā, he māwhero mārama ina nui te ihirangi o te Fe2O3, ina iti rānei te nui o te rere.
