Optical microscopy images of the dissolution of sawdust at three temperatures (100, 120, and 140 °C) as a function of treatment time. The first row of images shows the specimens before heating, while the other rows show the specimens at different times after reaching the target temperature. The black colour in the images is air inside sawdust particles that is released when the system temperature raises over 100 °C
