Pu'ina ni lopa tioata
O lo'o mata'eta'e mata'itala fana fa'atauga e fa'aaogaina e fa'amama ma fa'aiila mea u'amea.O lopa tioata e lelei le mautu o vailaʻau, faʻapitoa le malosi faʻainisinia ma le maaa.O le mea lea, i le avea ai o se mea faʻafefete, e sili atu ona lelei nai lo isi mea faʻafefe.E masani ona faʻaaogaina mo le faʻafefeina o le oneone, aveese le ele ma le faʻamalo o vaega o masini faʻapisinisi, faʻamalo ma faʻamamaina o vaalele ma afi afi afi, lau ma uʻamea.Fa'aliga fa'aiila fana fa'a'ai lopa tioata, fa'asino igoa: 1.51-1.64;Maaa (Mohs) 6–7;Kalave fa'apitoa: 6 g / 2-4 cm2;SiO2 anotusi> 70%;Ta'amilosaga: > 90%.
