ESTUDIO DEL EFECTO DE LA TEMPERATURA EN EL TONO DE ESMALTES PIGMENTADOS SOBRE GRES. Temperature effect on tone of color enamel in gres porcellanato applications

Industry of ceramic decoration uses ceramic pigments and enamels in order to support the pigment to obtain coloration and tonal perseverance that it impacts in the acceptance or rejection of the ceramic piece on the part of the consumer. This work presents how temperature of the ceramic enamels varies tone of ceramic pieces. It was ready and it applied an enamel ceramic on gres porcellanato support for serigraph-paintbrush method to several samples and different temperatures. Results determine the tonal variation of the samples, applying a technical spectrophotocolorimetric to determine the parameters CIE L*a*b *, and the reflectance spectral.
