Altogether, 37 samples were collected, of which 33 samples passed pre-processing criteria and chemical treatment and were dated. Two of them were Palaeolithic charcoals of likely sedimentary origin, one wood sample corresponded to a younger intrusion, six represented ‘old wood’ likely aged about 200 years when built in, and 24 originated from ‘young wood’ presumably not older than 50 years at the time of building. This highlights the need to collect large enough sample set when dating architectural remains using charcoals or wood splinters. As a rule of thumb, collecting at least 10 samples is recommended; otherwise, the dating might not be feasible at all or may yield unrealistically old estimates, by as much as 200 years for medieval castles.

Here we showed that the gas proportional counting technique can be used for bone samples, processed only by a simple ABA method, and ethanol, distilled from wine samples. The feasibility of the described methods was verified by successful dating of 11 well-preserved vertebrate bones of modern to 21 kyr BP age excavated from different caves in Slovakia from which collagen was also extracted, as well as by determination of 14C concentration in two modern western Slovakia vintages, which matches well the atmospheric Δ14C level for the respective region and grape vegetation period. Various empiric factors affecting the yield of the thoroughly tested procedures used for processing of samples and their optimization parameters are discussed as well.
