About This Product
Sizing is the treatment that makes paper resist the absorption of water and ink. Paper that is poorly sized soaks up water quickly, while well-sized paper takes up very little. In the Cobb water absorption test, a known area of paper is exposed to water for a set time, and the weight of water absorbed is found. The result is used to judge the sizing of the paper, although the method is not recommended for writing paper. Water absorption also depends on the porosity of the paper.
