Key Points from DP

  1. Paper revolutionized how information was distributed in the world and was much cheaper and more efficient to make than its predecessor, parchment, which was made from animal skin.

  2. The polymer that makes up paper is cellulose, and these polymers hydrogen bond with each other to make paper a cohesive surface. When paper is wet, water molecules sit between cellulose polymers and prevent them from bonding with each other. As water is squeezed out, the cellulose is forced to hydrogen bond with itself.

  3. Handmade paper is very labor intensive but appeals to artists because of the process and the quality of the paper.

  4. Sizing is a technique that prevents paper from “bleeding” when ink is applied to it. One way to size paper is to soak it in a gelatinous solution.

  5. The raw material for hand paper making is usually cotton or hemp, but in the past paper has been made from rags. The phrase “from rags to riches” comes from this concept, because rags could be used to make paper which was a valuable commodity in the past.
