Thanks to Lindybeige for this
Thanks to Lindybeige for this collab! Check out Lloyd's Channel: lindybeige
Before the use of coins and currency was established, how did Merchants and Traders determine the quality and validity of precious metals being offered to them in trade for goods and services? Lloyd from the Lindybeige Channel explains how this worked.
Modern methods to examine the molecular structure of things can be done non-destructively by a method called X-Ray Fluorescence. Before that, Nitric Acid was used to determine the quality of precious metal such as gold. Long ago, the use of a stone called a Touchstone was used to tell the difference between an item the user knew was authentic with a precious metal being offered to them. Today, the term touchstone has endured to mean something a person can rely on as a gauge of quality.

|| ABOUT ||
Today, getting what you need is as easy as a trip to the store. From food to clothing, energy, medicine, and so much more, Andy George will discover what it takes to make everything from scratch. His mission is to understand the complex processes of manufacturing that is often taken for granted and do it all himself. Each week he’s traveling the world to bypass the modern supply chain in order to harvest raw materials straight from the source. Along the way, he’s answering the questions you never thought to ask.
