Variation of moisture content of some varnished woods in indoor climatic conditions
In this study, moisture change of varnished wood of black poplar (Populus nigra) and yellow pine (Pinus silvestris L.) used in indoor climate conditions with central heating in Trabzon (Turkey) were investigated. 300 mm length wood specimens, with cross section of 12.5 mm in tangential and in radial...
