Umuhondo wa Chrome, uzwi cyane nka chromate y'ubutare (PbCrO₄), ni ibara ry'umukara kandi ritangaje rizwi cyane mu mateka kubera ibara ryaryo rikomeye. Yakozwe bwa mbere mu 1809 n'umuhanga mu bya shimi w'Umufaransa Louis Nicolas Vauquelin, yamenyekanye vuba nk'uburyo buhendutse bwo gusimbura amabara gakondo y'umuhondo nka orpiment. Izina ry'iryo bara rikomoka kuri chromium, ikintu cyavumbuwe mu gihe Vauquelin yageragezaga kuri crocoite y'ubutare, isoko karemano ya chromate y'ubutare.
Gukora umuhondo wa chrome bisaba inzira yo kuvura hakoreshejwe imiti. Umunyu wa lisansi uhura n'ibintu bya chromate cyangwa dichromate mu gisubizo cy'amazi, bigakora uduce duto twa chromate ya lisansi. Mu guhindura imiterere y'imikorere, abakora bashobora gukora amabara atandukanye, kuva ku muhondo wa primrose werurutse kugeza ku macunga menshi kandi akungahaye. Uduce duto dutanga amabara yoroheje, mu gihe uduce duto dutanga amabara yijimye. Kugira ngo hongerwe uburyo bwo gutuza no gukora neza, hakunze gukoreshwa uburyo bwo kuvura ubuso, burinda ibara kwangirika kw'ibidukikije.
