O le uiga o le Ituaiga K o lona malosi e tete'e ai i le fa'a'okesaita, ma e tatau ona fa'aaogaina pea i se siosiomaga fa'a'okesaita ma le le gaoioi. O le vevela mo se taimi umi e 1000℃ ma le vevela mo se taimi pu'upu'u e 1200℃. O le vevela sili ona fa'aaogaina lautele lea i totonu o thermocouples uma; (e le mafai ona fa'aaogaina e fa'aitiitia ai le siosiomaga kesi).
