A supervised fuzzy method is described and efficiently applied for the first time in this study. The advantages of the new approach for the characterization and classification of various Roman potteries on the basis of their mineral composition has been explored. The new classification robust approach allows more relevant conclusions to be drawn, finding more specific groups and a better characterization of Roman potteries using their degrees of membership to each fuzzy partition and solving in this way some discrepancies. The efficiency of the supervised fuzzy method was also estimated by the values of quality performance features obtained applying different fuzzy quality criteria and highly illustrative graphs. The parameters of the prototype (class centre) illustrate much better than, for example, arithmetic mean the specific characteristics of each class, and the degrees of membership allow a rationale comparison of the similarity and differences of Roman pottery samples investigated.

Keywords: supervised fuzzy method, prototypes, fuzzy quality criteria, Roman pottery, spectrometry
