The importance of understanding the terminology of collagen and gelatine in the study of parchment

Research in the field of conservation utilizes the literature of the arts, humanities and sciences to help understand material change and to improve conservation practice. The challenge associated with the use of such a broad range of literature is the process of extrapolation, where oversimplification of unfamiliar concepts and the misuse of terminology can occur. The unintended consequences of misuses in language can lead to the original meaning being misconstrued and evolution of terminology which is unhelpful for the conservation profession and others beyond its disciplinary boundaries. Here we examine, discuss and define the meanings of terms related to collagen and gelatine commonly used in heritage science, in particular with respect to parchment artefacts. We also present the context in which terminology is used and potential pitfalls of the terminology to avoid future ambiguities.
