February - Getting to the point

This month we are going back to the Bronze Age to a time when the production, fabrication, development and use of metals was very much in its infancy.  The late Bronze Age knife or razor shown below was found near Swaffham and was probably cast in a two-piece clay mould around 800 to 700 BC.

The metal is Bronze which is comprised of copper and tin alloyed together, but it probably also contained a deliberate addition of lead, as the metal-workers of the time had already discovered that this made the metal more fluid when molten and therefore improved the casting process (1).  As the drawing shows the leaf-shaped blade is still in surprisingly sharp condition.

November - Shaping Up

November's Find of the Month is this fantastic Middle – Late Bronze Age anvil.

Bronze Age anvils are very unusual finds, probably because the metalworkers who used them were easily able to melt down broken ones to create new objects.

Almost every surface of this example would have been used to work bronze or gold, with either of the two ‘beaks’ being used to secure the anvil to a wooden block so the other could be used to shape the metal. Each working surface has a different form allowing a wide variety of shapes to be created using just this one anvil.

At the time this anvil was in use, the number and type of personal ornaments made and worn by Bronze Age people increased, and this anvil would have been used to make some of them. The metalworker who used it would have been highly skilled and was probably seen as powerful, important or even as having a religious role in society. We suspect this because the way Bronze Age tools were treated shows they had a meaning or significance beyond their use as tools, suggesting the people who made them had a role which extended beyond their skills as craftspeople.
