Mwala wophulika (womwe umadziwika kuti pumice kapena porous basalt) ndi chinthu chothandiza komanso chogwirizana ndi chilengedwe, chomwe ndi mwala wamtengo wapatali wopangidwa ndi magalasi ophulika, mchere, ndi thovu pambuyo pa kuphulika kwa chiphalaphala.Mwala wophulika uli ndi mchere wambiri komanso kufufuza zinthu monga sodium, magnesium, aluminium, silicon, calcium, titaniyamu, manganese, chitsulo, nickel, cobalt, ndi molybdenum.Ndiwopanda kuwala ndipo ili ndi mafunde akutali a infrared magnetic.Pambuyo pa kuphulika kwa chiphalaphala chopanda chifundo, pambuyo pa zaka masauzande ambiri, Anthu akupeza phindu lake.Tsopano yakulitsa minda yake yogwiritsira ntchito ku minda monga zomangamanga, zosungira madzi, kugaya, zosefera, makala amoto, kukongoletsa malo, kulima popanda dothi, ndi zinthu zokongoletsera, zomwe zimagwira ntchito yosasinthika m'mafakitale osiyanasiyana.

Mwala wophulika ndi mtundu watsopano wa zinthu zomwe zimagwira ntchito komanso zachilengedwe, zomwe ndi mwala wamtengo wapatali wopangidwa ndi magalasi ophulika, mchere, ndi thovu pambuyo pa kuphulika kwa mapiri.Mwala wophulika uli ndi mchere wambiri komanso kufufuza zinthu monga sodium, magnesium, aluminium, silicon, calcium, titaniyamu, manganese, chitsulo, lithiamu, faifi tambala, cobalt, ndi molybdenum.

Makhalidwe ake ndi kulemera kopepuka, mphamvu zambiri, kutsekemera kwa kutentha, kuyamwa kwa mawu, kukana moto, asidi ndi alkali kukana, kukana kwa dzimbiri, kulibe kuipitsidwa, kulibe ma radiation, ndi ma pores ang'onoang'ono pamtunda, monga pores pakhungu.Kulowetsedwa mumafuta a injini kumatha kuyamwa pang'onopang'ono zigawo zamafuta ofunikira, kenako ndikuzimasula pang'onopang'ono pakhungu, kuwalola kulowa m'thupi la munthu.Kuphatikiza apo, imaphatikizidwa ndi zinthu zopangidwa ndi mafuta ofunikira komanso njira zapadera zochotsera mpanda, miyala ya Volcano yakhala ikugwiritsidwa ntchito kwambiri muzamankhwala ndi zokongoletsa m'zaka zaposachedwa chifukwa amatha kuthana ndi zovuta zambiri zapakhungu.
