Chapter 13: Elements as Money

Katana Lowman

Chapter 13 Synopsis

In the book “The Disappearing Spoon”, in chapter 13 the main focus was on how elements can be used for trade and for money. The chapter tells about the history of trading metals and the elements’ origins. Chapter 13 also describes how money such as coins has shaped the world. This chapter admits to past counterfeits that have rose due to fake metals that look very similar to the other coins in circulation. Without the elements mentioned in chapter 13, the world would be tremendously different as we know it today.

The elements that were mentioned in chapter 13 were: Zinc; Gold; Tellurium; Europium; and Aluminium. The elements mentioned are all metals. In the beginning of the chapter, it is mentioned that coin trade began in ancient Turkey in 700 B.C. In today’s world we still can get payed for finding rare earth elements such as gold,(Au); and aluminum,(Al). As time goes on, and Earth grows older, rare earth elements will become even harder to find, and the cost for trading will rise exceptionally.

Overall Summary for Chapter 13

In the book the elements that were mentioned in chapter 13 were gold; aluminum; tellurium; europium; and zinc. Gold is mentioned in the chapter several times. In the chapter, it talks about the “Gold- Rush” in the United States, and about how “fool’s gold” looked similar to gold but it was not like gold chemically. Zinc is an important element that we use in our everyday life. We use zinc in medicine and in cosmetics. Zinc is even in batteries! Aluminum is a very ductile, (bendy) material that people use to package things, like for lunch, or even to bake something. Tellurium is able to decrease corrosion of copper and stainless-steel which helps people to have longer-lasting cookware . Europium is a very good absorber of neutrons and has a compound which is inside of T.V.’s. I have learned that in chapter 13 that elements do serve a purpose in our everyday lives.
