Jordana Mariot Inocente, Ana Filipa Neves, Pedro Mantas, Alexandre Zaccaron, Vitor de Souza Nandi, Renato Dagostim PasiniWith the industrial revolution and market demand, the ceramic coating manufacturing process was a need to produce materials with closest shades, that is, without abrupt variations of color in the same product type. The difficulty in reaching this goal is very difficult because of the many variables in the production process. However, with the development of technical studies in the field of glazing and dyes this is possible. In this work we were compared ceramic glazes (matt, opaque and transparent) with varying amounts in weight green dye (1%, 3%, 5% and 7%), and analyzed the effect that the addition of this dye has on each glaze. For this study we used the techniques of characterization of XRD, dilatometry, colorimetry and surface roughness. The results obtained through XRD analysis showed that the zirconia is the carrier vehicle of the green chromophore. The dilatometry was changed with the addition of 7% of the dye lowering the coefficient of up to 4 points. The colorimetric analysis indicated that the green was well developed, and were saturated with 7% dye in matte and opaque glazed, and the surface roughness did not change with the percentage dye added.
