Alum rosin size

Description

A type of acid size for paper containing a rosin-alum mixture. Starting in the 1820s, Aluminum sulfate, or papermakers alum, was added to rosin size causing it to flocculate to the cellulosic fibers in the pulp solution. However, residual alum in the paper produces an acidic environment that accelerates the degradation of paper.
