In a weird sequence of amnesiac time-travel events, you are transported to 16th century Germany where the only practical fuel (or energy source) is firewood. Suppose you are given a piece of Copper which contains silver in small quantities. As luck would have it, you have a good quantity of Lead at your disposal.
