The steps followed for the characterization of the floor tile assemblage from La Elvira site (Virrey del Pino, La Matanza, Province of Buenos Aires) are presented. These ceramic floor tiles are colloquially known as “French floor tiles” according to a traditional 19th century commodity. The sample reunites 56 units, including both complete and fragmented specimens. Size was measured, refitting and trademarks were registered. Thickness was selected as a comparative variable, computing the average, minimal and maximal values within the entire sample; then, for each trademark-identified subgroup of tiles, average thickness and frequency of units within discrete thickness ranges was calculated, looking for the diversity, if any, within and between trademarks. According to the data collected, a slight trend towards size standardization is perceived. As for the designs, on the other hand, specimens of La Elvira match the repertoire of known designs for the City of Buenos Aires. Finally, La Elvira’s role in the international commercial network is discussed considering the diversity of the trademarks in the sample.
