Picture a pot of boiling water with a lid covering it. The steam rises to the lid, condenses, and little water droplets form. Now picture a pot of molten metal with a lid covering it. What happens when you heat the pot hot enough? The same process occurs, except the lid, instead of being coated with water gets coated with a layer of evaporated and resolidified metal. When this process is done in a vacuum, the lid will be covered with a smooth coat of resolidified metal. The pot, in this case, is called a crucible, and the lid is the deposition point. If you changed the shape of a crucible to look like a flattened Viking boat and made it smaller, it would be an evaporation boat.

Wait, how do crucibles get hot enough to boil metal?

Different types of metal have different m
