In his quest to make a camera from scratch, this guy extracted silver from ore

Andy from How to Make Everything is on a mission to make a photograph from scratch. What that means is that he is going to make a camera and a photographic plate from raw materials (like wood, minerals, and ore) that he's gathered. In this video, Andy extracts five grams of silver from ore he collected, which can be used as the light-sensitive coating for a photographic plate.
