Resumen
The present work focuses on gypsum mortar manufactu red in traditional kilns and used historically as exterior rendering. A documentation survey has been carried out followed by an experimental analysis using geological techniques. Conclusion shows that traditional gypsum is formed by anhydrite and inert active impurities (crystalline amorphous silica; cl ays and hydraulic phases) produced by the craft manufacture process of the system, in a kiln with a 200ºC to 1000ºC temperature interval, and continuo us fuel supply during 36 hours. Anhydrite together wit h the hydraulic phases set at consecutive time peri ods and with the presence of moisture improve the physi cal and mechanical properties of the final product. The hydration system is of great complexity and sho ws a very slow kinetics when in presence of impurities
