The brown and black pigments are generally synthesised from different powders such as iron (111) and chromium (111) oxide powders. In this study, iron-chromium pigments by using grinding waste from cast iron foundry as iron source and chromite mixtures were produced. The pigments were synthesised from mixing different ratios of grinding waste and chromite with modifier oxides and calcined at different temperatures. The resulting pigments were used in both transparent glazes of wall tile and satin glazes of floor tile and were characterised using x-ray diffraction (XRD). The colours obtained after glazing are defined as L*a*b* parameters by using Spectrophotometer.
