“…The interest in laser cleaning applications for a variety of organic heritage and archaeological materials such as parchment, leather, paper, and basketry has grown considerably in the last decade (Arif et al, 2013;Andreotti et al, 2007;Elliott et al, 2007;Elnaggar et al, 2011). However, to our knowledge, this is the first comprehensive evaluation of the potential of laser cleaning intervention for papyrus.…”

There has been a growing interest in laser cleaning applications for a variety of organic materials such as paper, parchment, textiles, and leather during the last decade. However, archaeological organic materials, notably papyrus, have rarely been investigated. This contribution examines whether removal of burial encrustation can be justified in view of its short-term and long-term effects on the substrate. To examine this, tests using mock objects have been performed. Using artificially soiled and archaeological papyrus samples, optimization of laser cleaning parameters using a picosecond laser (1064 nm, various operating conditions) was attempted. Optimization was based on colorimetry, optical microscopy, scanning electron microscopy, Fourier transform infrared spectroscopy, and cellulose degree of polymerization data, both before and after accelerated degradation. In papyrus, there is no clear damage threshold, and substrate degradation can always be observed and is comparable in treated (cleaned) and untreated (soiled) objects. Therefore, the decision on whether to clean papyrus using lasers is predominantly based on aesthetic and treatability (e.g. need for consolidation) criteria.

“…To clean a dusty rostrum, a stiff brush should be used, such as hog's hair, possibly with the aid of a vacuum (Storch 2003, Elliott et al 2007, Daudin-Schotte et al 2010. The rostrum should be brushed from the distal end to the proximal end in order to avoid catching or lifting the placoid scales.…”

Sawfish rostra are commonly found in historic natural science collections, yet there is a scarcity of guidance on their preservation. Rostra are cartilaginous with teeth-like scales. The function and structure of sawfish rostra as well as key mechanical and chemical issues need to be considered for their appropriate care in museum collections. Possible routes of decay are discussed, and methods for the care and conservation of rostra in museum collections are suggested. The species of sawfish can be determined by the morphology of the rostral structure. Physical damage, due to the nature of the material and from handling, often causes deterioration of rostra.
