A 1.4. Scar tissue

Scar tissue is scarred wounds the surface texture (colour, relief) of which differs significantly from the remaining surface of the parchment.
Scars and wounds in the animal’s skin allude to illnesses and poor animal care, and thereby the poor quality of the raw skin. The more significant the document, the less scar tissue occurs on the surface, because parchment made from the best possible skins were used for important documents. With its different texture, car tissue alters the appearance and durability of the parchment.
