Rocket Fule Mixtures

Rocket Fuel Basic Formula

65%        KNO₃
35%        Powdered Sugar or Powdered Sorbitol

Better Rocket Fuel for Melting

61%        KNO₃
4%          NH₄NO₃ 
35%        Powdered Sugar or Powdered Sorbitol
1 mL       Glycerol/100g of mix (Add after partly melted)
Note: NH₄NO₃ and glycerol make the mixture melt at a lower temperature and pour easier.

Better Catalyzed Rocket Fuel for Melting

61%        KNO₃
4%          NH₄NO₃
35%        Powdered Sugar or Powdered Sorbitol
1 mL       Glycerol/100g of mixture (Add after melted)
4 g          Fe₂O₃/100g of mixture

Delay Mix Basic=Add 3g baking soda to 20g of basic rocket fuel mix

7g           Powdered Sorbitol
3g           NaHCO_3
or

56.5%    KNO₃
30.4%    Powdered Sorbitol
13.0%    NaHCO₃

Something to try with delay mix to make it pour better:
