Medieval to Early Modern Papermaking

Prior to the invention of the paper machine (~ 1800), all paper was handmade. Teams of three skilled, European artisans (vatman, coucher, layer) were capable of producing ~1500 sheets in a day.

Gelatin (produced by boiling animal bones or skins) was first used as an external surface sizing for paper in 1337 and continued as a dominant sizing agent of all European papers through the mid-19th century. Sizing reduces the tendency of dry paper to absorb liquid, allowing inks and paints to dry remain on the surface of the paper, rather than be absorbed into the paper. Thus, sizing provides a more consistent painting and writing surface.
