Abstract

At the moment, only partial maximally generalized information about bog oak is known in the world, which cannot be used to create an information base on the properties, main species and age differences of bog oak. If we draw a parallel with the wood of an ordinary (not bog) oak, then we can draw the following conclusion. The variety of oak has about 600 species. About twenty species of oak are common in the CIS countries. Each of the known types has various structural changes in the process of staining, which entails a change in the qualitative and technical characteristics of the material. This fact is complicated by the age differentiation of bog oak wood. In one territorial area where deposits of bog oak have been explored, there may be trunks, parts of trunks aged from 300 to 8,110 years (the maximum age of bog oak found in Belarus by the GODO “Trans-Center” enterprise, specializing in the extraction and processing of natural bog oak). The age of bog oak directly affects its future quality characteristics. Also, in one explored area, deposits of bog oak wood of different age groups may have species differences, since over a period of several thousand years, oak forests have changed depending on climatic conditions, changes in the mineral composition of soils, depth of occurrence, etc. For a complete understanding of bog oak wood and the staining process, it is necessary to take a comprehensive approach to its study, which was the purpose of this work.
