THERMAL MODIFICATION OF Eucalyptus grandis WOOD: VARIATION OF COLORIMETRIC PARAMETERS

The color modifications in Eucalyptus grandis thermally modified wood were investigated. One hundred eighty specimens (10 x 10 x 200 mm) were prepared and thermally modified in an electric kiln for 4 and 8 h at 180-240ºC. The color parameters (L*, a*, b*, C*, h* and ΔE) were determined by t...
