In keeping with the tradition of the previous two workshops held in Turku/Aland (Finland, 2010) and in Mallorca (Spain, 2012), the 3rd Mortar Dating Workshop to be held in Padova in 2014 wishes to offer a dynamic forum to the scientific community working on historical mortar and plaster dating. It is expected that the leading groups in the field will summarize the results carried out by the method of 14C dating in the last decades, offering a systematic overview of the existing methods and protocols of analysis. Ample space will be devoted to the illustration of state-of-the-art techniques, persisting problems, and future perspectives. Applications to historical mortars and plasters from different ages and geographical areas are welcome. A special session will focus on comparison with other dating techniques, especially those based on stimulated luminescence, TL and alternative methods.
