Paper is made from bamboo, cotton rags, and some other materials. Today it is made in large quantities in paper mills. The materials are first soaked in water and then are reduced to pulp. Sulphur and some other chemical substances are used in making the pulp. It is then made clean and lime is added to it to give it the white look. Next, the pulp is spread in thin sheets and dried, and finally, cut into pieces of various shapes and sizes. All these things are done by machinery. In this way we get paper that we use for writing and printing. Many paper mills are found all over India. The Titaghur Paper Mills near Calcutta is the oldest and biggest of them all.
