Abstract: This paper deals with the technical and methodological sampling problems of lumps of not completely mixed lime putty in mixtures, in order to obtain a suitable material for the radiocarbon dating of mortars and plasters. Sampling of this type of lumps, in fact, allows us to be able to use a suitable material for the radiocarbon dating of lime mixtures (e.g. mortars, plasters, lime bed of mosaics, frescos paintings, etc.) because in this way it is possible to avoid the contamination problems deriving from sources of carbon such as the "14Cdead" of limestone sand or of not completely burned limestone. From an archaeological point of view, this sampling procedure gives the possibility to obtain an accurate radiocarbon dating for each piece of masonry considered without any considerable damage.
