Book on chemicals

Read to learn about volatile chemicals.

Read it to learn how to make a Chemical compound from ingredients you find at the Digsite. These ingredients include: Ammonium nitrate, Nitroglycerin, Ground charcoal, and Arcenia root.

If lost or destroyed, a new copy can be obtained from the bookcases in the Exam Centre or from the bookcase in your Player-Owned House made through Construction.

When in your bookcase, this text is called Volatile Chemicals.

Below is the text you can read from within the book.
In order to ease the mining process, my colleagues and I decided we needed something stronger than picks to delve under the surface of the digsite. As I already had an intermediate knowledge of Herblore, I experimented with certain chemicals and invented a compound of tremendous power that, if subjected to a spark, would literally explode. We used vials of this compound with great effect, as it enabled us to reach further than ever before. Here is what I have left of the compound’s recipe:

• 1 measure of ammonium nitrate powder;
• 1 measure of nitroglycerin;
• 1 measure of ground charcoal;
• 1 measure of ?

Unfortunately the last ingredient was not noted down, but we understand that a certain root grows around these parts that was used to very good effect…

It's about chemicals, judging from its cover.
