The ingredients of paper are cellulose fiber (e.g. wood pulp, linen rags), water, bleaching agent, fillers (e.g. chalk), "sizing" (e.g. clay surface coating for glossiness and ink absorbency). The paper is spread on fine mesh wire screens, pressed between rollers to squeeze out excess water, and allowed to dry to remove the remaining water. Some paper also contains acids (usually from processing to make wood pulp) and if these are not neutralized the paper will turn brown and become brittle over time. The bleaching agent makes the paper white and decolorizes inks from recycled paper.
