He mea hanga te paura alumina ma te parakore iti-konutai konutai ma te whakarewa i te pāmahana teitei, te whakamatao whakamatao, katahi ka kuru.Ko te kirikiri konumohe waikura konumohe ma i raro i te tino whakahaere kia mau tonu te tohatoha o te witi me te ahua rite.
He whaiti te tohatoha rahi o te witi o te paura alumina ma.I muri i te hanga i te tukatuka, he parakore te paura corundum ma he witi tonu, he koi nga taha me nga kokonga, he pai te huri, he kanapa oro teitei.Ko te kaha o te huri he nui ake i nga abrasive ngawari penei i te silica.
