Abstract :Black ceramic colorants were prepared from mixing Ni-Co composite, chromite and magnetite mineral as raw materials. The colorant mixture prepared for this purpose was added to stoneware ceramic glazes at 10%,15% and 20% respectively. The prepared colorant added glazes were ground in the jet mill for 15 minutes and sieves. Glazes applied to the stoneware bodies and then fired at 1200 °C in an industrial ceramic kiln. Color values of colorants and colored glazes were measured L*a*b* with a spectrophotometer device. It has been observed that this prepared colorant has similar properties with the color values of the black colorants used in the sector. As a result, it has been shown that the black colorant obtained can be used as a colorant in Stoneware glaze recipes without causing any problems or defects in the final product.Keywords : Stoneware, Glaze, Materials, Characterization, Colorant
