This book introduces readers to chemical elements, focusing on metals that are part of our daily lives. Metals are found in our blood, the earth beneath us, and are essential in cookware and technology. The book explores practical applications, such as why chromium is added to steel, how armor and crystal glass are made, why antique paintings darken, and the property platinum gives to mirrors.
