Inyuma y’iterambere ryihuse mu myaka iheze, imashini y’amakara y’amakara yinjiye mu bidukikije bikomeye. Ariko rero, ingingo ngenderwako rusangi z’ugushikiriza imashini - ntizigeze zishika ku rugero rwo hejuru rw’ugucapura kandi buhoro buhoro ziriko ziragenda zija ku rugero rwo hejuru no mu guhindura uko bisanzwe. Muri iki gihe, imashini ya kera - ishobora guca mu bice vy’amakara, amakara y’ubushuhe, hagati{6}}
Ibiharuro vy’amakara bifise ubushuhe buke ni amakara afise ubushuhe bungana n’amadegre 380 n’amakara y’amakara arenga 60%, nk’ubwoko butandukanye bw’amakara atandukanye. Kuva ku kugaragara, nta n’ivyuma vy’ivyuma vy’agaciro kanini - y’ubushuhe, kandi irafise ubugoyagoye kandi ifise ubukomezi buke cane. Bishobora gusenyuka no gumeneka bitagoranye, kandi ingaruka mbi ni mbi cane. Ikoreshwa cane cane mu nganda no mu buhinzi (nk’amahinguriro y’isuku ry’i silikoni), gushusha n’inkono ishushe, n’ibindi.
Ikarata y'ubushuhe igera ku rugero rwo hejuru rw'ubushuhe ruri munsi ya 1000℃n'uburebure burengeye 380℃, umuyagankuba ungana n'ibice 75%, n'ubushuhe rusangi bugera ku 600℃. Kuva ku kugaragara, nta tandukaniro ryinshi riri hagati y’ubushuhe buringaniye n’ubushuhe buke, ariko niwabigereranya mu kuboko kwawe, uzosanga ubushuhe buri hagati buremereye kuruta ubushuhe buke bw’ubunini bumwe. Ahanini ikoreshwa mu gukora barbecue, kandi ishobora no gukoreshwa mu nganda no mu buhinzi, gushusha n’inkono ishushe, n’ibindi.
Ikarata y’ubushuhe bwinshi yerekeza ku mashure akomoka ku bushuhe buri hejuru ya 1000 degrés , n’ivyuma bihoraho vy’umuyagankuba (carbole) uhoraho ungana na 85%. Ikozwe mu gukaraba mu ifuru y’ubushuhe bwinshi. Biragoye kandi biraremereye iyo bifashwe n’ukuboko, birashobora kurohama mu mazi, kandi birashobora gutuma umuntu agira ijwi ry’icuma iyo akomanga. Ifise umuyagankuba munini, ibintu bishobora guhinduka bitoya n’ibintu vy’ivu, nta n’urubeya iyo bituritse, n’ubushobozi bwo guhangana n’ugusha bungana incuro 3 bw’amakara y’ubushuhe buke n’incuro 2 z’amakara y’ubushuhe buri hagati. Ni vyiza ku bihe vyose aho amakara akoreshwa, cane cane ku mabara y'imbere mu nzu no gushora hanze.
