Umuringa (igikombe) ni ikintu cy'icyuma, nacyo nikintu cyinzibacyuho, Icyongereza Umuringa wa 29. Umuringa wa Atomic wa 29. Ibara ry'umuringa wa kane Umucungamutungo, umushinga muremure n'amashanyarazi, rero umugozi n'amashanyarazi, ibice bya elegitoroniki, ibikoresho bikunze gukoreshwa cyane, birashobora no gukoreshwa nkibikoresho byubaka, birashobora gukoreshwa muburyo bwinshi bwa alloys. Umuringa Holoys ufite imitungo ihanitse kandi irwanya amashanyarazi make, muri zo zingenzi ni umuringa n'umuringa. Umuringa nawo nicyuma kiramba gishobora gutungwa inshuro nyinshi utangiza imitungo yayo.

Gufungura umunyuzi wumurinzi, uruganda rwumuringa rukunze kugaragara, akenshi ubururu muri ions yabo ya hydtion nicyatsi muri chlorine yabo ligands. Ninkomoko y'amabara ya mabuyelt nka Azurite na turquoise kandi bakoreshejwe mumateka nkamateka nka pigmen. Ruswa yinzego zubaka umuringa zitanga verdigris (karori yibanze yumuringa). Ubuhanzi bwo gushushanya cyane cyane bukoresha umuringa numuringa - ikubiyemo pigment.

Umuringa wari umwe mubyuma bya kera cyakoreshejwe numuntu. Nko mu bihe bya mbere, abantu batangiye kwanjye gufungura - umuringa kandi akayikoresha kugirango akore intwaro, ibikoresho nibindi bikoresho. Gukoresha umuringa byagize ingaruka zikomeye ku iterambere ryumuco wabantu ba mbere. Umuringa ni ibyuma biboneka mu bukene bw'isi n'inyanja. Ibirindira mu bukorikori bw'isi ni nko 0.01%, no ku kubitsa umuringa ku giti cye, ibirimo umuringa birashobora kugera kuri 3% ~ 5%. Benshi mu muringa muri kamere baboneka mubice bita amabuye y'umuringa.

Igikorwa cyumuringa gifite intege nke, kandi reaction yicyuma hamwe na sulfate yumuringa irashobora gusimbuza umuringa. Umuringa urasabwa muri Nonoxidening acide.
