Uamea uamea 347 1.4550
O lenei pepa faʻamatalaga e faʻatatau i le uamea uʻamea 347 / 1.4550 vevela ma le malulu o loʻo i luga o le laupepa, faʻamau ma faʻamau, oloa semi-uma, tootoo ma vaega faʻapea foʻi mo faʻauʻu uʻamea ma faʻafefe mo faʻainisinia ma faʻainisinia lautele.
Fa'atatauga
Mo vaega faufale e tatau ona fa'asa'o i le fa'asili e o'o atu i le 1050°C ma fa'ateleina fa'a'ai i le a'afiaga o kasa sulfur, aemaise i luga a'e o le 900°C, e matua maualalo lava.
