Bleigießen is Germany's traditional New Year's Eve fortune-telling custom involving molten metal or wax.
In the practice, a small piece of material is heated and dropped into cold water. The resulting hardened shape is interpreted as a symbolic prediction for the coming year. The German name literally refers to “lead pouring,” although modern versions often use wax or another safer substance.
Lead versions became controversial because lead is toxic, especially when heated or handled incorrectly. For that reason, many contemporary kits use wax or tin alternatives, and consumers are advised to follow safety instructions and local regulations.
The shapes do not have one universally fixed meaning; interpretations vary among guides and families. Bleigießen is therefore different from a formally standardized religious ritual. Its appeal comes from combining a New Year's gathering with playful prediction and conversation.
