“…As previously demonstrated, CLSM enables the recognition of features crucial for wood identification on various objects (Balzano et al, 2019;Čufar et al, 2019), and this study confirms that the method is also useful for identification of charcoal wood without special sample preparation.…”

Wood identification of barbecue charcoal from commercial packages of three retailers (B1, B2, B3) in Slovenia and Croatia was performed with help of Confocal Laser Scanning Microscopy (CLSM). CLSM enabled us to image key identification features of charcoal wood that were compared with light micrographs of wood from the reference collection. Product B1 contained charcoal made exclusively of beech wood (Fagus sylvatica) and the declaration indicated the address of the producer, in Serbia which allowed traceability of the wood. The selection of wood species in product B2, consisted of red oak (Quercus cerris or Q. rubra), black locust (Robinia pseudoacacia), and cherry (Prunus avium), which could originate from Serbia, and it did not contain tropical wood as stated on the package. Product B3 contained wood from at least four (sub)topical species which could not be exactly identified to species/genus level. The declaration on the product did not allow traceability of wood. As the risks of illegal logging are high for wood of (sub)tropical origin, our results support the initiative that the monitoring of the charcoal trade should be covered by the EUTR - European Timber Regulations.

“…Through analysis of the microscopic structure, samples 1 through 4 were the same wood species, identified as willow (Salix spp.) (Sauter and Wellenkamp 1988;Čufar et al 2019;Wagenführ and Wagenführ 2021), as shown in Fig. 3.…”

The Nantong Ancient Ship refers to an ancient Chinese wooden ship of the late Ming Dynasty excavated in Nantong city in December 2022. This paper identifies the wood and discusses its related analysis. Wood samples extracted from the Nantong Ancient Ship were studied from the viewpoints of anatomy, physics, and chemistry. Microscopic identification results concluded that willow and Chinese fir were the main wood species used to make this ship. The content of holocellulose in the ancient wood was only 37.9 to 38.9%, while the content of lignin was 55.2 to 56.4%. The cellulose crystallinity of ancient wood was 39 to 42% lower than that of healthy recent wood. Fourier transform infrared (FTIR) spectra revealed that the deterioration of ancient wood caused cellulose and hemicellulose degradation, but no apparent lignin alteration. The results could provide a basis for drawing up a conservation plan for the Nantong Ancient Ship. They could also provide a reference for the research and conservation of other archaeological shipwrecks in China.

The goal of this work is to suggest a method for assessing the state of salvaged glued laminated timber and deciding whether it is appropriate for reuse. After conducting a thorough analysis of the wood pathology, a decision tree mind map was created. This was followed by the application of this methodology to evaluate a salvaged glulam frame obtained from a demolition site. To ensure the reliability of this approach, laboratory-based ex situ tests were carried out. A working protocol was established for obtaining a sample of the salvaged timber, and its characteristics were identified by examining the species, density, type of adhesive and its shear resistance, as well as the mechanical properties in the bending of both single and double laminates of timber. The results concluded that the glulam under investigation can be reused. The results revealed that the wood was spruce, with a density of 420 ± 45 kg/m3 under dry conditions. The glue used was melamine–urea–formaldehyde with a shear strength of 7.37 ± 1.79 MPa, which is below the standard threshold. The results of the bending strength and modulus of elasticity show that the single laminations and glulam are class C16 and class GL20H, respectively.
