The present study deals with the analysis of the characteristics of ceramic
wall and floor tiles on the basis of their quality parameters: breaking
force, flexural strenght, absorption and shrinking. Principal component
analysis was applied in order to detect potential similarities and
dissimilarities among the analyzed tile samples, as well as the firing
regimes. Correlation analysis was applied in order to find correlations among
the studied quality parameters of the tiles. The obtained results indicate
particular differences between the samples on the basis of the firing
regimes. However, the correlation analysis points out that there is no
statistically significant correlation among the quality parameters of the
studied samples of the wall and floor ceramic tiles.[Projekat Ministarstva
