Those with a steady hand will get better sec-tions with the thinner, double-sided razor blade, but very thin blades are too flexible. Circular slices about 34 mm thick are cut off, using a razor blade. For making longitudinal sections, the cork slice is cut across the diameter at an angle (Fig. This protocol decreases the time required for all aspects of microtechnique tissue processing, including fixation (24 hr to 15 min), dehydration (73 hr to 10 min), and infiltration (96 hr to 3 hr). Ø  Delicate materials should be supported to withstand the cutting force. Ø  Example: Ultra-thin sectioning for electron microscopy (TEM). The cubes are boiled in water until waterlogged, i.e. Pith tends to become soggy when wet, and cork can contain unexpected sclereids which blunt the knife, but on the whole we prefer cork. Rotary microtome: Knife remains stationary, specimen moves. After treatment, the wood must be washed in running water for several hours. Certain leaves contain silica bodies (particularly those of grasses and sedges) which blunt the microtome knife and tear the section.
