Evaluation of Material Characteristics of Xylite – Part 2. Characterization of Drying Defects

Xylite very much has the appearance of precious wood species with dark heartwood and also has some physical and aesthetical properties of wood, required nowadays for making valuable products. Xylite, with well recognizable and preserved wood structure, was used for studying the drying kinetics and d...
