000002363 520__ $$2eng$$aThe present work focuses on gypsum mortar manufactured 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; clays and hydraulic phases) produced by the craft manufacture process of the system, in a kiln with a 200ºC to 1000ºC temperature interval, and continuous fuel supply during 36 hours. Anhydrite together with the hydraulic phases set at consecutive time periods and with the presence of moisture improve the physical and mechanical properties of the final product. The hydration system is of great complexity and shows a very slow kinetics when in presence of impurities.
