About the blog: What Things Are Made Of


The United States relies on imports for dozens of commodities in everyday use. Often enough, that reliance is 100%. In this book I aim to provide awareness of the hidden geology and mineralogy behind common things, and to develop an appreciation for the global resource distribution that underpins our society. While concerns about oil import reliance are in the news every day, our needs for other minerals are comparable and are typically unknown even to technologically aware Americans.

US lacks rare earths

Just a link today, to an editorial comment by a professor of mineral and material science, Dr. Courtney Young, on US dependency on rare earths - and our lack of them.

The rare earths occupy many pages in What Things Are Made Of.
