Break Charge

burst charge

A break charge, also known as a burst charge, is a small explosive charge inside an aerial shell that ignites explosively at the proper height, almost instantly producing a large volume of fiery gasses which ignites and spreads the contents of the shell.

Typical break charges (in approximate order from most to least powerful) are made from:

  1. Flash powder    
  2. H3 on a medium such as rice hulls    
  3. KP on a medium such as rice hulls  
  4. Granulated black powder, or Corned black powder    
  5. meal coated on a medium such as rice hulls

A stronger break can be achieved by adding a small amount of booster, of which following are typical:

  1. Perchlorate Flash powder
  2. Whistle mix
  3. Nitrate Flash powder
