This is the kind of passion project I love to see. These recreations of the Signs of Power from "The Dark is Rising" series were made as a gift by David Stay. Each of the six is forged from a different element (iron, stone, bronze, etc.). The recreations are made from exactly the same materials, save for the "Fire" sign. The book version is solid gold. The prop is gold leaf over lead.
Here's a shot of the fire sign being cast from molten metal.
