I-iron oxide, ekwaziwa ngokuba yi-ferric oxide, i-limonite etshisiweyo, i-ochre etshisiweyo, i-iron red, i-iron red, i-red powder, i-Venetian red (inxalenye ephambili yi-iron oxide), njl. Ifomula yekhemikhali i-Fe2O3, enyibilikayo kwi-hydrochloric acid, yi-red-brown powder. I-red-brown powder yayo yi-pigment ephantsi, ebizwa ngokuba yi-iron oxide ebomvu kushishino. Isetyenziswa kwipeyinti, kwi-inki, kwirabha nakwamanye amashishini njenge-catalyst, i-polishing agent yeglasi, ilitye elinqabileyo kunye nesinyithi, kwaye ingasetyenziswa njengezinto zokwenza isinyithi.
