Abantu benshi bakunda kwambara imitako y'ibyuma by'agaciro nka bracelets, urunigi, impeta, impeta, n'ibindi. Ibyuma nyamukuru bikoreshwa mumitako ni zahabu na platine.
Intambwe yambere mugukora imitako yagaciro yicyuma nugushonga ibyuma byagaciro binyuze aitanura.Hariho ubwoko bwinshi bw'itanura ryo gushonga ku isoko.Tuzahura nibibazo bimwe na bimwe muguhitamo itanura.Ntabwo dutanze'ntumenye itanura ryo gushonga rikwiranye nibikoresho byacu byo gushonga.
Mu nganda zimitako, birasanzwe gukoresha itanura ryinjira kugirango ushongeshe ibyuma.Niba rero ushaka guhitamo aitanura, ugomba kwitondera ingingo zikurikira:
Mubyukuri, itanura rya induction rikoreshwa muburyo bukoreshwa hagati yumuriro no mumashanyarazi menshi.Ubushyuhe ntarengwa bwo gutanura itanura hagati ni 2600°C. Ubushyuhe ntarengwa bw'itanura ryinshi ni 1600°C. Niba rero ushaka kugura amashyiga ya induction, biterwa nicyuma ushaka gushonga.
Gushonga kwa zahabu ni 1064°C, gushonga kwa platine ni 1768°C, naho gushonga kwa feza ni 961°C. Niba rero ushonga zahabu na feza, ugomba gukoresha itanura ryinshi ryo gushonga, ntabwo ari itanura rito.Niba ubushyuhe bwo gushonga buri hejuru cyane, bizatera impinduka mubwiza bwicyuma.Icyuma gishongeshejwe kirashobora kwanduzwa.
Nukuvugako, mugihe duhisemo itanura rishonga, dukeneye kandi kwitondera ubwoko bwingenzi.Hariho ubwoko bubiri bwo kubambwa: grafite ingirakamaro na quartz ibamba.Ukurikije ubushyuhe bwo gushonga, umusaraba wa grafite ukoreshwa mu ziko ryinshi.Kandi quartz ingirakamaro kumatara yo hagati.Quartz irwanya ubushyuhe bwinshi kuruta grafite.Twabibutsa ko ifeza ishobora gukoreshwa gusa mumashusho ya grafite, ntabwo ari muri quartz.Kuberako ifeza yifata na quartz ikabuza ifeza gushonga burundu, noneho izakomeza gukomera kandi itera igihombo kinini.
