Past Uses and the "Mad Hatter" Story
For a long time, mercury(II) nitrate was used in a special process. It helped turn fur into felt, which was then used to make hats. This process was common in the 18th and 19th centuries.
However, the people who worked with mercury(II) nitrate often got very sick. They breathed in mercury fumes and absorbed the chemical through their skin. This caused mercury poisoning. Symptoms included shaking, memory problems, and changes in behavior. This is where the saying "mad as a hatter" came from. It was a real problem for hat makers back then. Today, we know how dangerous mercury compounds are. Because of this, mercury(II) nitrate is no longer used for making felt.
