Roman glues would have been organic, although possibly not vegetable-based as these may not have offered sufficient strength – more likely they were fish- or animal-based. Animal-based adhesives have been used throughout history, in concentrated form as glue, and in more dilute form as a size, to seal surfaces prior to application of painted surfaces. This is traditionally made by boiling up rabbit skins, animal hooves and similar inedible animal by-products. It would not only provide a strong bond, holding together the layers of ply, but would serve to fuse the board to a surface fabric or leather coating, sealing the surface prior to painting. Being of animal origin, on combustion, this type of glue could appear visually and chemically similar to the ‘bubbly char’ reportedly found on the surface of the Doncaster shield board (Biek, 1978, 269).
