Colorimetric Gradation in RGB-Space as a Method for Detecting Structural Changes in Ceramic Materials

Resumo

This work describes the use of the color gradation method for the determination of structural differences in the bulk of a traditional ceramic sample based on the contribution of the R, G, and B components of light and their distributions. The method is based on statistical analysis of R, G, B values corresponding to coordinates of the individual cells, and a reasonable selection of taxa with representative cells with specific characteristics. It is shown that in this case the main color component is red (R), which monitors the state of iron and the degree of completeness of phase transformations in the material during technological processes.
