Ibuye ry'ibirunga (bakunze kwita pumice cyangwa basalt basalt) ni ibikoresho bikora kandi bitangiza ibidukikije, ni ibuye ryiza cyane ryakozwe n'ikirahure cy'ibirunga, imyunyu ngugu, n'ibibyimba nyuma yo guturika kwikirunga.Ibuye ry'ibirunga ririmo imyunyu ngugu myinshi hamwe na sisitemu ya sodium, magnesium, aluminium, silikoni, calcium, titanium, manganese, fer, nikel, cobalt, na molybdenum.Ntabwo ari imirasire kandi ifite imiyoboro ya magnetiki ya kure.Nyuma y’ibirunga bitagira imbabazi, nyuma yimyaka ibihumbi icumi, Abantu bagenda bamenya agaciro kayo.Ubu yaguye imirima ikoreshwa mu mirima nk'ubwubatsi, kubungabunga amazi, gusya, ibikoresho byo kuyungurura, amakara ya barbecue, gutunganya ubusitani, guhinga ubutaka, n'ibicuruzwa by'imitako, bigira uruhare rudasubirwaho mu nganda zitandukanye.

Ibuye ryibirunga ni ubwoko bushya bwibikoresho bikora kandi bitangiza ibidukikije, ni ibuye ryagaciro cyane ryakozwe nikirahure cyibirunga, imyunyu ngugu, nudusimba nyuma yo guturika kwikirunga.Ibuye ry'ibirunga ririmo imyunyu ngugu myinshi hamwe na sisitemu ya sodium, magnesium, aluminium, silikoni, calcium, titanium, manganese, fer, lithium, nikel, cobalt, na molybdenum.

Ibiranga ni uburemere bworoshye, imbaraga nyinshi, izimya ubushyuhe, kwinjiza amajwi, kurwanya umuriro, aside na alkali, kurwanya ruswa, nta mwanda, nta mirasire, hamwe nuduce twinshi duto hejuru, nkibibyimba ku ruhu.Kwinjiza amavuta ya moteri birashobora gukuramo buhoro buhoro ibice byingenzi byamavuta, hanyuma bikarekura buhoro buhoro kuruhu, bigatuma byinjira mumubiri wumuntu.Byongeye kandi, ihujwe n’ibicuruzwa bikomoka kuri peteroli hamwe nubuhanga bwihariye bwo kwangiza uruzitiro, amabuye y’ibirunga yagiye akoreshwa cyane mu buvuzi n’uburanga mu myaka yashize kuko ashobora gukemura ibibazo byinshi by’uruhu bibabaza.
