Mapigment esimbi oxide imhando yakakosha yemavara asina kugadzirwa, ayo chikamu chikuru chiri ma iron oxides. Anowanikwa semapigment echipiri pakukura asina kugadzirwa mushure me titanium dioxide uye mapigment epamusoro asina kugadzirwa ane mavara, achishandiswa zvakanyanya mumaindasitiri uye muhupenyu hwezuva nezuva.
Panyaya yemakemikari, zvinosanganisira zvikamu zvina: iron oxide tsvuku, iron oxide yero, iron oxide nhema, uye iron oxide brown. Pakati pazvo, iron oxide tsvuku ndiyo inonyanya kuwanikwa, ichiumba inenge 50% yehuwandu hweiron oxide pigments. Pamusoro pezvo, micaceous iron oxide, inoshandiswa se anti-rust pigment, uye magnetic iron oxide, yezvinhu zvekunyora magnetic, inowirawo mukati me iron oxide pigments. Mhando dzakasiyana dzeiron oxide pigments dzine mavara akasiyana-siyana nekuda kwemamiriro akasiyana eiron oxidation. Semuenzaniso, iron oxide tsvuku, inobva ku ferric oxide (Fe₂O₃), inoonekwa setsvuku; iron oxide yero, inobva ku hydrated ferric oxide (Fe₂O₃·H₂O), yeyero; uye iron oxide nhema, inova magnetite (Fe₃O₄), inoratidza dema.
Panyaya yekushanda kwayo, pigment ye iron oxide inoshamisa. Kuramba kwayo acid ne alkali kwakanaka kwazvo. Yakasimba zvikuru kana ichienzaniswa nehuwandu hwakasiyana hwe alkali nezvinhu zvinowanzoshandiswa pakuvaka zvakaita se simende ne lime mortar, pasina kukonzera upfu hwe simende kana kukanganisa simba rayo. Zvisinei, inonyunguduka zvishoma nezvishoma mu acid yakasimba, kunyanya kana ichidziya uye ine huwandu hwakawanda. Nezvekudzivirira chiedza nekupisa, pigment ye iron oxide yakajairwa inogara mukati meimwe tembiricha. Semuenzaniso, iron oxide yero inoshanduka kuva tsvuku kana ichidarika 130°C, uye iron oxide red inodzika kusvika kutsvuku yakasviba pamusoro pe300°C. Kunyange zvakadaro, mabhizinesi mazhinji ikozvino akagadzira zvigadzirwa zvine mashandiro akanaka zvinogona kutsungirira tembiricha yakakwira. Kuramba kwayo mamiriro ekunze kwakanaka kwazvo, isina kukanganiswa zvakanyanya nemamiriro ekunze akadai sekutonhora, kupisa, kuoma, uye hunyoro mumhepo, zvichiita kuti ive yakakurumbira mukushandiswa kwekunze. Uyezve, yakagadzikana mumagasi akasviba, hainyungudike mumvura, mafuta emaminerari, mafuta emiriwo, uye akawanda organic solvents, uye hairatidzi kupinda.
