Real View TG measurement of wood

A square-cut wood (width: about 3.3 mm) was measured in air atmosphere. While the TG and DTA curves indicate thermal decomposition of cellulose between 200 and 350°C, the images show the sample color starting to change below 200°C. In the oxidative decomposition at about 450°C, the color turned to white with some flame spark due to intense reaction.
