Historic canon restoration, France. Close-up of an 18th Century Prussian bronze canon from the Battery Royal des Invalides, Paris, France, being restored. Here, the canon is being heated with a torch in order to completely remove any moisture from the metal. It will then have a protective wax applied while it is still warm.
