Papermaking

Joseph Jerome de la Lande, Art de faire le Papier. (Paris: Academie de Sciences, 1761)


This illustration shows the construction of the papermaker's mold and deckle. The mold is dipped into a vat of pulp, lifted up, and shaken as the water drains through the screen. The paper fibers are left behind on top of the screen, and, if the sheet is well-made, the mat of fibers will have formed strong mechanical and chemical bonds with each other. Note the watermark is formed from wire and sewn onto the top of the mold.
