Itshe lentaba-mlilo (elivame ukubizwa ngokuthi i-pumice noma i-basalt enezimbotshana) liyinto esebenzayo futhi evumelana nemvelo, okuyitshe eliyigugu kakhulu elinezimbotshana elakhiwe ingilazi yentaba-mlilo, amaminerali, namabhamuza ngemva kokuqhuma kwentaba-mlilo.Itshe lentaba-mlilo liqukethe inqwaba yamaminerali kanye nezakhi zokulandelela ezifana ne-sodium, i-magnesium, i-aluminium, i-silicon, i-calcium, i-titanium, i-manganese, insimbi, i-nickel, i-cobalt, ne-molybdenum.Ayinamisebe futhi inamaza kazibuthe e-infrared.Ngemva kokuqhuma kwentaba-mlilo okungenalusizo, ngemva kwamashumi ezinkulungwane zeminyaka, Abantu baya ngokuya bethola ukubaluleka kwayo.Manje isinwebe izinkambu zayo zokufaka isicelo ukuze ifinyelele emikhakheni efana nezakhiwo, ukongiwa kwamanzi, ukugaya, okokuhlunga, amalahle esoso, ukunakekelwa kwezwe, ukutshala okungenamhlaba, kanye nemikhiqizo yokuhlobisa, idlala indima engenakushintshwa ezimbonini ezihlukahlukene.

Itshe lentabamlilo liwuhlobo olusha lwezinto ezisebenzayo nezivumelana nemvelo, okuyitshe eliyigugu kakhulu elinezimbotshana elakhiwe ingilazi yentaba-mlilo, amaminerali, namabhamuza ngemva kokuqhuma kwentaba-mlilo.Itshe lentaba-mlilo liqukethe inqwaba yamaminerali nezinto zokulandelela ezifana ne-sodium, i-magnesium, i-aluminium, i-silicon, i-calcium, i-titanium, i-manganese, insimbi, i-lithium, i-nickel, i-cobalt, ne-molybdenum.

Izici zayo isisindo esilula, amandla aphezulu, ukufakwa kwe-thermal, ukumuncwa komsindo, ukumelana nomlilo, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala, akukho ukungcola, akukho misebe, kanye nezimbotshana eziningi ezincane phezulu, njengezimbotshana esikhumbeni.Ukucwiliswa kuwoyela wenjini kungathatha kancane kancane izingxenye zikawoyela ezibalulekile, bese kuzikhulula kancane kancane esikhumbeni, kuzivumele ukuthi zingene emzimbeni womuntu.Ngaphezu kwalokho, ihlanganiswe nemikhiqizo kawoyela ebalulekile eyakhiwe kanye nezindlela ezikhethekile zokuqeda ubuthi kocingo, amatshe e-Volcanic aye asetshenziswa kakhulu kwezokwelapha kanye nobuhle eminyakeni yamuva njengoba akwazi ukuxazulula izinkinga eziningi zesikhumba ezicasulayo.
