Paʻepaʻe corundum ma alamanuia alumini oxide paʻu e pei o mea mata, i le arc ina ua mavae le maualuga o le vevela liusuavai i luga 2000 tikeri ina ua maeʻa malulu, ina ua uma ona tuʻimomomoina, vavae ese maneta i uʻamea, sieve ua vaevaeina i ni vaega eseese tele, o le oloa maeʻa o loʻo i ai le lanu mafiafia, maaa maualuga, foliga maaleale maai Angle.Mea e leai se u'amea ma maualuga le mama, maualuga pa'epa'e, maualuga ma'a'a ma eseese vaega sa'o lapopo'a.Saito-saito oloa faasologa oneone: talafeagai mo le gaosiga ceramics, resin consolidation abrasive meafaigaluega ma olo, polesi, sandblasting, saʻo lafo (teu faafaigaluega lafo corundum faapitoa) ma isi.Vaega o le oneone ma le pauta lelei faasologa: e masani ona faaaoga mo le gaosiga maualuga-grade mea refractory.
