Two materials are studied to synthesize a vinyl painting. Iron ore is an iron pigment with an oolithic structure containing phosphorus. The second material is a steel by-product. The raw materials proprieties were studied by chemical, particle size, thermal, XRD and spectrophotometric analysis. The iron contents of the pigment and scale are respectively 53.18% and 73.83%. The grindability of scale is better than that of the pigment. The particle volume distribution is 0.7 to 32 µm for scale and 0.6 to 40 µm for pigment. TGA and DTA tests show that the pigment loses weight with phase dissolution by consuming energy and the scale gains weight with the formation of a new phase when the temperature increases. The SEM of the scale showed a homogeneous structure of iron oxide grains ranging from 1 to 10 μm. XRD analysis shows that the iron in the pigment is in the form of (Fe₂O₃) and FeO (OH)) and very little (Fe₂SiO₄). The iron in the scale is in the form of (FeO, Fe₂O₃ and Fe₃O₄). Spectrophotometric tests show that the two materials have no absorption and their reflection is maximum (100%) in the visible range.
