How did Bormann fuse work?
The artillerist used a metal punch to pierce the thin metal at the desired time marking. This exposed a section in the horseshoe-shaped horizontal mealed powder train (3), which is covered by a thin sheet of tin. When the cannon discharged, the flame from the explosion ignited this powder train.
How did Civil War cannonball fuses work?
It was driven into a metal or wood fuze plug mounted in the fuze hole of the projectile. The second system employed a soft metal housing containing a powder train. burned down through the set number of seconds, the fuze flame would enter the powder chamber inside the projectile and cause the projectile to explode.

How did a cannonball explode?
When the cannon fired, the flame of the propelling charge wrapped around the ball and ignited the exposed powder train, which in turn sparked the bursting charge after burning for the selected number of seconds. These shells and spherical case shot were designed to explode only when a flame reached the interior charge.
