An invention that I learned about during presentations was Paper presented by Caitlyn Evans. Caitlyn told us all about the history and impact of paper. We learned that humans have been writing down their notes since the beginning of time and many early civilizations used tree bark or clay to jot things down. Early paper was made of these materials.
I learned that the first paper was made in 200 BCE in China where a paper prayer was created on a brick of someone's home. It was mostly used for religious purposes, the government, or wealthy business owners who used this old fishing nets and bamboo to make paper. Fibers were collected a soaked and lined with stone and then grounded into pulp which was then poured into a rectangular mold. Water is drained and the paper is left to dry in the sun and removed from the mold.Caitlyn also talked about Korea, Japan and Italy in the invention of paper. In Korea, they used a process of animal-powered pulping mills to create a paper mold out of bamboo and wooden boards that made drying paper sheets easier. Japan used paper for Korean Buddhist monks and they created mass printing of paper. Italy had very well-established paper mills. They made paper out of cotton and linen as well as perfecting paper molds using wood and metal frames.
In 1869, paper-making in the United States was made out of wood fibers. Which was created at the first paper mill in Culhuacan, Mexico. Today, most paper is made out of wood due to it being more affordable and very available compared to cloth and other materials.Caitlyn also told us about the impacts paper had on society. We use paper everyday, whether it's for writing a to-do list, grabbing a napkin, or even making a purchase with cash. Paper has changed our worlds, and thanks to the innovations from many ancient cultures, we are now able to use it daily.
