Ibuye ry’ibirunga (rizwi cyane nka pumice cyangwa basalt ifite imyenge) ni ibikoresho bikora neza kandi birengera ibidukikije, rikaba ari ibuye ry’agaciro gakomeye rigizwe n’ibirahure by’ibirunga, imyunyu ngugu, n’udusimba nyuma y’iruka ry’ikirunga. Ibuye ry’ibirunga rigizwe n’imyunyu ngugu myinshi n’ibintu bike nka sodium, manyeziyumu, aluminiyumu, silikoni, kalisiyumu, titaniyumu, manganese, icyuma, nikeli, kobaltiyumu, na molybdenum. Ntirigira imirasire kandi rifite imiraba ya rukuruzi ya infrared. Nyuma y’iruka ry’ikirunga ritagira impuhwe, nyuma y’imyaka ibihumbi n’ibihumbi, abantu barimo kugenda bavumbura agaciro karyo. Ubu ryaguriye imirima yaryo mu mirima nko mu bwubatsi, kubungabunga amazi, gusya, ibikoresho byo kuyungurura, amakara ya barbecue, ubusitani, ubuhinzi butagira ubutaka, n’ibicuruzwa by’imitako, rigira uruhare rudasimburwa mu nganda zitandukanye.

Ibuye ry'ibirunga ni ubwoko bushya bw'ibikoresho bikora neza kandi bitangiza ibidukikije, rikaba ari ibuye ry'agaciro gakomeye rigizwe n'ibirahure by'ibirunga, imyunyungugu, n'udusimba nyuma y'iruka ry'ibirunga. Ibuye ry'ibirunga rigizwe n'imyunyungugu myinshi n'ibintu bike nka sodium, manyeziyumu, aluminiyumu, silikoni, kalisiyumu, titaniyumu, manganese, icyuma, lithiyumu, nikeli, kobalti, na molybdenum.

Ibiranga ni ibiro byoroheje, imbaraga nyinshi, ubushyuhe butuma ibintu bishyuha, ubushobozi bwo kwinjiza urusaku, ubushobozi bwo kurwanya aside na alkali, ubushobozi bwo kurwanya ingese, ubushobozi bwo kwirinda umwanda, ubushobozi bwo kutagira imirasire, n'imyenge myinshi mito ku buso, kimwe n'imyenge ku ruhu. Kwinjiza amavuta ya moteri bishobora kwinjiza buhoro buhoro ibice by'amavuta y'ingenzi, hanyuma bikayarekura buhoro buhoro ku ruhu, bigatuma yinjira mu mubiri w'umuntu. Byongeye kandi, bihuzwa n'amavuta y'ingenzi yakozwe hamwe n'uburyo bwihariye bwo gukuraho uburozi ku ruzitiro, amabuye y'ibirunga yagiye akoreshwa cyane mu buvuzi no mu bwiza mu myaka ya vuba aha kuko ashobora gukemura ibibazo byinshi by'uruhu bibabaza.
