Good Morning all:
In our collections we have a 6#  cannon ball that still has its fuse.  
We suspect it is still filled with gunpowder also. It was recovered 
during a metal detector survey last fall and may date to the Civil War 
era.  We have been getting mixed messages regarding the safety of having 
such an item in our collection.  Does anyone know about the safety and 
stability of such an item?
Thank you
