ABSTRACT
This article aims to explain in detail the methodology and initial results from “Study of gypsum and traditional plaster in Spain. Deposits, quarries, kilns and traditional architecture, state of conservation and proposals of itineraries for promotion and diffusion” commissioned in 2016 by the Spanish Ministry of Education, Culture and Sport through the Cultural Heritage Institute of Spain. A detailed description is provided here of the objectives, phases and sources consulted for this study. Special importance is attached to those which have made it possible to locate deposits, quarries and kilns or gypsum transformation centres throughout Spain in order to understand the importance of gypsum in the Spanish constructive tradition. Finally, the main general results of the study are detailed, as well as details specifically addressing types of extraction, kilns, gypsum materials and their multiple uses in the past.
