O le tuufaatasiga fa'akemikolo o mea e opeopea o le silicon dioxide ma le aluminium oxide. E tele ona uiga e pei o ni fasi manifinifi, gaogao, mama, malosi tele, tete'e atu i le ofuina, tete'e atu i le vevela maualuga, fa'amafanafana ma tete'e atu i le afi. E fa'aaogaina lautele i se tasi o mea mata mo le alamanuia e tete'e atu i le vevela.
