Glue ascribable to a group of adhesives of animal origin, essentially identifiable with parchment glue and, as such, characterized by fewer impurities with respect to skin glue. It has been amply used since antiquity for the preparation of gesso and for the confection of tempera paints. Filippo Baldinucci (1681) describes it as it was made beginning with "the binding of sheep parchment, that the tanners make at the ends of the leather….the ends are vulgarly called 'limbellucci,' or 'carniccio,'and not being touched too much with the knife of the tanner, they are fatter and thus more adapt to make glue."
