Inside our laboratory, extra paraffin is faraway from the underprocessed block by inserting the block in the embedding Centre's molten paraffin for 15–20 min; the tissue is then changed in the cassette, set again while in the automated tissue processor beginning in formalin, and reprocessed. The paraffin that also remains from the tissue will give some protection against overprocessing. While reprocessing may be necessary in some situations as described above, the caliber of reprocessed tissues is usually nonetheless considerably suboptimal.
In 1770, Hill described a microtome or ‘cutting motor’ made by Cummings for the sectioning of woody tissue [12].
