A mixture of water and dissolved paper pulp produced during the stock preparation phase of papermaking. Pulp must be dissolved in water and constantly agitated before undergoing refining to keep paper fibers from prematurely clotting, which would have a deleterious effect on the paper produced. The loading of non-fibrous additives is also facilitated when fibers are suspended in water.
In ink manufacturing, slurry refers to the mixture of the liquid ink vehicle and solid pigment particles that undergo mixing and milling.
