Part of a dandy roll.
Watermarks were first used in late thirteenth century Italy as a means of identifying the manufacturer or client with the product, and are still widely used today with the added function of being a security measure.
With the mechanisation of papermaking in the late eighteenth century, the means by which the watermark was applied had to be changed from a flat design on the paper mould to a cylindrical design on a roller which moved over the paper. The design of the
watermark is raised slightly above the mesh of the dandy roll. When in contact with the paper surface, the design causes a slight impression which means that the thickness of the paper at that point is not as great as elsewhere on the roll. When held to
the light, the design shows clearly.
This dandy roll has the embossed inscription "Sawston Granta Parchment Tub Sized Air Dried".
