The study of the stone sculpture production process is subject to the preservation and visibility of tool traces and surface finishes. In this article it is proposed that the parameters developed in conservation for the diagnosis of surface stone alteration processes can be used as descriptors to isolate the attributes of postproduction conditions and their influence on variation in the appearance of stonework traces. It shows how the application to a case study served to determine the alterations that contribute to the deterioration of carving traces, the selection of the best-preserved areas for recording, and the retrieval of information for increasing the sample number. The results of fracturing patterns caused by a stress sector in the sculpture body are shown. Certain sets of alterations occurred together, either affecting the integrity of the carving groove or increasing the texturing finish of the polished surface.
El estudio de los procesos de producción litoescultórica está sujeto a la conservación y visibilidad de las huellas de talla y acabados de superficie. En este artículo se propone que los parámetros desarrollados en conservación para la diagnosis de los procesos de alteración de la superficie de la piedra pueden ser empleados como descriptores para aislar los atributos de afecciones sufridas post-producción y su influencia en la variación de la apariencia de las huellas de trabajo litoescultórico. Se muestra cómo la aplicación a un caso de estudio sirvió para la determinación de las alteraciones que concurren en el deterioro de dichas huellas y la selección de las áreas mejor conservadas para posteriores análisis. Los resultados muestran patrones de fracturación provocados a partir de un sector de tensión en el cuerpo escultórico, mientras que ciertos conjuntos de alteraciones ocurrieron conjuntamente, ya sea afectando la integridad de la sección del surco de talla, o bien incrementando la texturización en los acabados de superficie pulidos. Si bien se trata de conclusiones preliminares, el estudio constituye un primer paso para un mapeo que sea capaz de cuantificar el grado en que las alteraciones de la piedra borran las marcas de producción escultórica.
