Re: Hard Tissue
One of the factors that influence this is how the tissue was originally
grossed. Pieces of tissue that are thinner on one edge than the other have a
greater tendency to chop out than if the piece is an even "block" (often
difficult with fresh unfixed tissue). By orientating the tissue when
embedding so that the smallest area comes in contact with the knife first
also helps. This means that instead of the longest axis of the tissue being
parallel to the edge of the block, the tissue is embedded, so that it is
"diamond" shaped. Hope that this helps, it is difficult to get a spacial
concept over without pictures.
