“…As highlighted by Macdonald and colleagues [63], impression accuracy is limited by "the intrinsic texture of the moulding material", resulting in a general smoothing of the original surface texture. Moreover, air could be trapped into the paste during the moulding process, resulting in circular smooth craters [65]; although, this was very easily identifiable at all scales of magnification (e.g., Figure 13 T1 and T3; Figure 14 stereomicroscope; Figure 17 stereomicroscope; and Figure 20 SEM). The accuracy of the moulds could also be influenced by the roughness and moisture of the artefacts' surface and by the environmental conditions (room temperature and humidity).…”

This article presents an analytical procedure developed to replicate, document, and analyse the formation and evolution of use-wear traces on task-specific ground stone tools. The purpose of this study is to build a reference collection for wear patterns that occurred during the processing of vegetal resources, specifically those compatible with the MIS 3 period. To create the collection, riverine slabs and pebbles were utilised and various aspects related to their use in the transformation of aerial and underground plant organs were explored. Moreover, the feasibility of using perishable supports, such as a wooden base, for processing tasks was examined. The experiments explored the transformation of pebble stone surfaces during repeated cycles of processing plant organs by monitoring and recording the features at fixed intervals. Several variables that affect the surface texture, morphology, distribution, and extent of use-wear traces are identified and discussed. The influential factors under control included the petrographic and morphological characteristics of the unused stones, the type and amount of transformed vegetables, and the duration of the process, as well as monitoring human factors. The documentation strategy applied at various stages of the experiment was found to be suitable for tracing the cumulative development of wear. The replicative collection was tailored to the morphological and petrographic characteristics of the ground stone tools retrieved from the level attributed to the Prut River culture of Brînzeni I, a cave site located in NW Moldova.
