  • RTI is a photographic method that allows to enhance any unevenness on the surface ofan object. In archaeology, the RTI method is used for various purposes, for instance, to study superficial markings on ceramic artefacts and to understand their possible causes (natural unevenness of the materials, manufacturing techniques, intended use). This article describes a research that has been conducted thanks to the RTI method on some ceramic artefacts dating back to the Bronze Age, from the village located in Via Ordiere, in Solarolo (RA). The research aims to test the limits of use of this instrument and its actual potential to give information on certain aspects of the production process of a ceramic artefact, such as the tools used to refine the surface (smoothing or polishing). Moreover, the RTI images have been tested as auxiliary tool for archaeological design of lithic artefacts from the same sites (arrowheads). The first part of the article is dedicated to the methodological aspects of the research: the processing chain, the tools and the time needed to complete each phase of the work. In the second part, the results of the research and the possible developments are discussed. The points of strength and the limits of this method are both summarised in the last section of the article.
