Mtundu wa iron oxide wobiriwira ndi iron oxide yellow umasiyana popanga
Iron oxide green ndi iron oxide yellow ndi mitundu yopangidwa kuchokera ku ayoni achitsulo ndi ayoni okosijeni. Pali kusiyana kwa mitundu yawo panthawi yopanga. Popanga chitsulo chobiriwira chobiriwira, chimapangidwa makamaka kuchokera ku ayoni achitsulo ndi ayoni wa okosijeni kudzera muzochita zama mankhwala. Kawirikawiri, mtundu wa iron oxide wobiriwira umakhala wobiriwira, umawoneka wobiriwira kapena wobiriwira. Pakupanga, kuya kwa mtundu wa pigment kumatha kuwongoleredwa ndikusintha zinthu monga momwe zinthu zimachitikira, ndende ya yankho, ndi mawonekedwe a oxide. Popanga iron oxide yellow, zochita za mankhwala zimagwiritsidwanso ntchito popanga ayoni achitsulo ndi ayoni okosijeni. Mtundu wa chitsulo okusayidi wachikasu nthawi zambiri umakhala wachikasu, wonyezimira wachikasu kapena lalanje. Poyerekeza ndi iron oxide green, iron oxide yellow ndi yopepuka mumtundu komanso imawonekera pang'ono. Mwachidule, kusiyana pakati pa mitundu ya chitsulo okusayidi wobiriwira ndi chitsulo okusayidi chikasu pakupanga ndondomeko makamaka zimaonekera mu machulukitsidwe ndi mtundu kuya kwa pigment. Njira yeniyeni yopangira ndi kusinthako idzakhudza mtundu, ndipo mtundu wa pigment ukhoza kuwongoleredwa pogwiritsa ntchito njira zoyenera.
